+/**
+ * The BreakIterator class implements methods for finding the location
+ * of boundaries in text. BreakIterator is an abstract base class.
+ * Instances of BreakIterator maintain a current position and scan over
+ * text returning the index of characters where boundaries occur.
+ * <p>
+ * Line boundary analysis determines where a text string can be broken
+ * when line-wrapping. The mechanism correctly handles punctuation and
+ * hyphenated words.
+ * <p>
+ * Sentence boundary analysis allows selection with correct
+ * interpretation of periods within numbers and abbreviations, and
+ * trailing punctuation marks such as quotation marks and parentheses.
+ * <p>
+ * Word boundary analysis is used by search and replace functions, as
+ * well as within text editing applications that allow the user to
+ * select words with a double click. Word selection provides correct
+ * interpretation of punctuation marks within and following
+ * words. Characters that are not part of a word, such as symbols or
+ * punctuation marks, have word-breaks on both sides.
+ * <p>
+ * Character boundary analysis allows users to interact with
+ * characters as they expect to, for example, when moving the cursor
+ * through a text string. Character boundary analysis provides correct
+ * navigation of through character strings, regardless of how the
+ * character is stored.  For example, an accented character might be
+ * stored as a base character and a diacritical mark. What users
+ * consider to be a character can differ between languages.
+ * <p>
+ * The text boundary positions are found according to the rules
+ * described in Unicode Standard Annex #29, Text Boundaries, and
+ * Unicode Standard Annex #14, Line Breaking Properties.  These
+ * are available at http://www.unicode.org/reports/tr14/ and
+ * http://www.unicode.org/reports/tr29/.
+ * <p>
+ * In addition to the C++ API defined in this header file, a
+ * plain C API with equivalent functionality is defined in the
+ * file ubrk.h
+ * <p>
+ * Code snippits illustrating the use of the Break Iterator APIs
+ * are available in the ICU User Guide, 
+ * http://icu.sourceforge.net/userguide/boundaryAnalysis.html
+ * and in the sample program icu/source/samples/break/break.cpp"

+ *
+ * <p>Characters can be accessed in two ways: as code units or as

+ * With UTF-16, all code points can be represented with either one
+ * or two code units ("surrogates").
+ * String storage is typically based on code units, while properties
+ * of characters are typically determined using code point values.
+ * Some processes may be designed to work with sequences of code units,
+ * or it may be known that all characters that are important to an
+ * algorithm can be represented with single code units.
+ * Other processes will need to use the code point access functions.</p>

+ * <p>ForwardCharacterIterator provides nextPostInc() to access
+ * a code unit and advance an internal position into the text object,
+ * similar to a <code>return text[position++]</code>.<br>
+ * It provides next32PostInc() to access a code point and advance an internal
+ * position.</p>
+ *
+ * <p>next32PostInc() assumes that the current position is that of
+ * the beginning of a code point, i.e., of its first code unit.
+ * After next32PostInc(), this will be true again.
+ * In general, access to code units and code points in the same
+ * iteration loop should not be mixed. In UTF-16, if the current position
+ * is on a second code unit (Low Surrogate), then only that code unit
+ * is returned even by next32PostInc().</p>
+ *
+ * <p>For iteration with either function, there are two ways to
+ * check for the end of the iteration. When there are no more
+ * characters in the text object:
+ * <ul>
+ * <li>The hasNext() function returns FALSE.</li>
+ * <li>nextPostInc() and next32PostInc() return DONE
+ *     when one attempts to read beyond the end of the text object.</li>
+ * </ul>
+ *
+ * Example:
+ * \code 
+ * void function1(ForwardCharacterIterator &it) {
+ *     UChar32 c;
+ *     while(it.hasNext()) {
+ *         c=it.next32PostInc();
+ *         // use c
+ *     }
+ * }
+ *
+ * void function1(ForwardCharacterIterator &it) {
+ *     UChar c;
+ *     while((c=it.nextPostInc())!=ForwardCharacterIterator::DONE) {
+ *         // use c

+/**
+ * Abstract class that defines an API for iteration
+ * on text objects.
+ * This is an interface for forward and backward iteration
+ * and random access into a text object.
+ *
+ * <p>The API provides backward compatibility to the Java and older ICU
+ * CharacterIterator classes but extends them significantly:
+ * <ol>
+ * <li>CharacterIterator is now a subclass of ForwardCharacterIterator.</li>
+ * <li>While the old API functions provided forward iteration with
+ *     "pre-increment" semantics, the new one also provides functions
+ *     with "post-increment" semantics. They are more efficient and should
+ *     be the preferred iterator functions for new implementations.
+ *     The backward iteration always had "pre-decrement" semantics, which
+ *     are efficient.</li>
+ * <li>Just like ForwardCharacterIterator, it provides access to
+ *     both code units and code points. Code point access versions are available
+ *     for the old and the new iteration semantics.</li>
+ * <li>There are new functions for setting and moving the current position
+ *     without returning a character, for efficiency.</li>
+ * </ol>
+ *
+ * See ForwardCharacterIterator for examples for using the new forward iteration
+ * functions. For backward iteration, there is also a hasPrevious() function
+ * that can be used analogously to hasNext().
+ * The old functions work as before and are shown below.</p>
+ *
+ * <p>Examples for some of the new functions:</p>
+ *
+ * Forward iteration with hasNext():
+ * \code
+ * void forward1(CharacterIterator &it) {
+ *     UChar32 c;
+ *     for(it.setToStart(); it.hasNext();) {
+ *         c=it.next32PostInc();
+ *         // use c
+ *     }
+ *  }
+ * \endcode
+ * Forward iteration more similar to loops with the old forward iteration,
+ * showing a way to convert simple for() loops:
+ * \code
+ * void forward2(CharacterIterator &it) {
+ *     UChar c;
+ *     for(c=it.firstPostInc(); c!=CharacterIterator::DONE; c=it.nextPostInc()) {
+ *          // use c
+ *      }
+ * }
+ * \endcode
+ * Backward iteration with setToEnd() and hasPrevious():
+ * \code
+ *  void backward1(CharacterIterator &it) {
+ *      UChar32 c;
+ *      for(it.setToEnd(); it.hasPrevious();) {
+ *         c=it.previous32();
+ *          // use c
+ *      }
+ *  }
+ * \endcode
+ * Backward iteration with a more traditional for() loop:
+ * \code
+ * void backward2(CharacterIterator &it) {
+ *     UChar c;
+ *     for(c=it.last(); c!=CharacterIterator::DONE; c=it.previous()) {
+ *         // use c
+ *      }
+ *  }
+ * \endcode
+ *
+ * Example for random access:
+ * \code
+ *  void random(CharacterIterator &it) {
+ *      // set to the third code point from the beginning
+ *      it.move32(3, CharacterIterator::kStart);
+ *      // get a code point from here without moving the position
+ *      UChar32 c=it.current32();
+ *      // get the position
+ *      int32_t pos=it.getIndex();
+ *      // get the previous code unit
+ *      UChar u=it.previous();
+ *      // move back one more code unit
+ *      it.move(-1, CharacterIterator::kCurrent);
+ *      // set the position back to where it was
+ *      // and read the same code point c and move beyond it
+ *      it.setIndex(pos);
+ *      if(c!=it.next32PostInc()) {
+ *          exit(1); // CharacterIterator inconsistent
+ *      }
+ *  }
+ * \endcode
+ *
+ * <p>Examples, especially for the old API:</p>
+ *
+ * Function processing characters, in this example simple output
+ * <pre>
+ * \code
+ *  void processChar( UChar c )
+ *  {
+ *      cout << " " << c;

+ * Traverse the text backwards, from end to start

+ * </pre>
+ * Traverse both forward and backward from a given position in the text.

+ * <pre>
+ * \code
+ * void traverseOut(CharacterIterator& iter, int32_t pos)
+ * {
+ *      UChar c;
+ *      for (c = iter.setIndex(pos);
+ *      c != CharacterIterator.DONE && (Unicode::isLetter(c) || Unicode::isDigit(c));

+ *          c != CharacterIterator.DONE && (Unicode::isLetter(c) || Unicode::isDigit(c));
+ *          c = iter.previous()) {}
+ *      int32_t start = iter.getIndex() + 1;
+ *  
+ *      cout << "start: " << start << " end: " << end << endl;
+ *      for (c = iter.setIndex(start); iter.getIndex() < end; c = iter.next() ) {
+ *          processChar(c);
+ *     }
+ *  }
+ * \endcode
+ * </pre>

+ */
+
+/**
+ * A <code>Locale</code> object represents a specific geographical, political,
+ * or cultural region. An operation that requires a <code>Locale</code> to perform
+ * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
+ * to tailor information for the user. For example, displaying a number
+ * is a locale-sensitive operation--the number should be formatted
+ * according to the customs/conventions of the user's native country,
+ * region, or culture.
+ *
+ * The Locale class is not suitable for subclassing.
+ *
+ * <P>
+ * You can create a <code>Locale</code> object using the constructor in
+ * this class:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ *       Locale( const   char*  language,
+ *               const   char*  country,
+ *               const   char*  variant);
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * The first argument to the constructors is a valid <STRONG>ISO
+ * Language Code.</STRONG> These codes are the lower-case two-letter
+ * codes as defined by ISO-639.
+ * You can find a full list of these codes at:
+ * <BR><a href ="http://www.loc.gov/standards/iso639-2/">
+ * http://www.loc.gov/standards/iso639-2/</a>
+ *
+ * <P>
+ * The second argument to the constructors is a valid <STRONG>ISO Country
+ * Code.</STRONG> These codes are the upper-case two-letter codes
+ * as defined by ISO-3166.
+ * You can find a full list of these codes at a number of sites, such as:
+ * <BR><a href="http://www.iso.org/iso/en/prods-services/iso3166ma/index.html">
+ * http://www.iso.org/iso/en/prods-services/iso3166ma/index.html</a>
+ *
+ * <P>
+ * The third constructor requires a third argument--the <STRONG>Variant.</STRONG>
+ * The Variant codes are vendor and browser-specific.
+ * For example, use REVISED for a langauge's revised script orthography, and POSIX for POSIX.
+ * Where there are two variants, separate them with an underscore, and
+ * put the most important one first. For
+ * example, a Traditional Spanish collation might be referenced, with
+ * "ES", "ES", "Traditional_POSIX".
+ *
+ * <P>
+ * Because a <code>Locale</code> object is just an identifier for a region,
+ * no validity check is performed when you construct a <code>Locale</code>.
+ * If you want to see whether particular resources are available for the
+ * <code>Locale</code> you construct, you must query those resources. For
+ * example, ask the <code>NumberFormat</code> for the locales it supports
+ * using its <code>getAvailableLocales</code> method.
+ * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
+ * locale, you get back the best available match, not necessarily
+ * precisely what you asked for. For more information, look at
+ * <code>ResourceBundle</code>.
+ *
+ * <P>
+ * The <code>Locale</code> class provides a number of convenient constants
+ * that you can use to create <code>Locale</code> objects for commonly used
+ * locales. For example, the following refers to a <code>Locale</code> object
+ * for the United States:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ *       Locale::getUS()
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <P>
+ * Once you've created a <code>Locale</code> you can query it for information about
+ * itself. Use <code>getCountry</code> to get the ISO Country Code and
+ * <code>getLanguage</code> to get the ISO Language Code. You can
+ * use <code>getDisplayCountry</code> to get the
+ * name of the country suitable for displaying to the user. Similarly,
+ * you can use <code>getDisplayLanguage</code> to get the name of
+ * the language suitable for displaying to the user. Interestingly,
+ * the <code>getDisplayXXX</code> methods are themselves locale-sensitive
+ * and have two versions: one that uses the default locale and one
+ * that takes a locale as an argument and displays the name or country in
+ * a language appropriate to that locale.
+ *
+ * <P>
+ * ICU provides a number of classes that perform locale-sensitive
+ * operations. For example, the <code>NumberFormat</code> class formats
+ * numbers, currency, or percentages in a locale-sensitive manner. Classes
+ * such as <code>NumberFormat</code> have a number of convenience methods
+ * for creating a default object of that type. For example, the
+ * <code>NumberFormat</code> class provides these three convenience methods
+ * for creating a default <code>NumberFormat</code> object:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     Locale myLocale;
+ *     NumberFormat *nf;
+ *
+ *     nf = NumberFormat::createInstance( success );          delete nf;
+ *     nf = NumberFormat::createCurrencyInstance( success );  delete nf;
+ *     nf = NumberFormat::createPercentInstance( success );   delete nf;
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * Each of these methods has two variants; one with an explicit locale
+ * and one without; the latter using the default locale.
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ *     nf = NumberFormat::createInstance( myLocale, success );          delete nf;
+ *     nf = NumberFormat::createCurrencyInstance( myLocale, success );  delete nf;
+ *     nf = NumberFormat::createPercentInstance( myLocale, success );   delete nf;
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * A <code>Locale</code> is the mechanism for identifying the kind of object
+ * (<code>NumberFormat</code>) that you would like to get. The locale is
+ * <STRONG>just</STRONG> a mechanism for identifying objects,
+ * <STRONG>not</STRONG> a container for the objects themselves.
+ *
+ * <P>
+ * Each class that performs locale-sensitive operations allows you
+ * to get all the available objects of that type. You can sift
+ * through these objects by language, country, or variant,
+ * and use the display names to present a menu to the user.
+ * For example, you can create a menu of all the collation objects
+ * suitable for a given language. Such classes implement these
+ * three class methods:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ *       static Locale* getAvailableLocales(int32_t& numLocales)
+ *       static UnicodeString& getDisplayName(const Locale&  objectLocale,
+ *                                            const Locale&  displayLocale,
+ *                                            UnicodeString& displayName)

+ *                                            UnicodeString& displayName)

+/**
+ * The Normalizer class supports the standard normalization forms described in
+ * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
+ * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
+ *
+ * The Normalizer class consists of two parts:
+ * - static functions that normalize strings or test if strings are normalized
+ * - a Normalizer object is an iterator that takes any kind of text and
+ *   provides iteration over its normalized form
+ *
+ * The Normalizer class is not suitable for subclassing.
+ *
+ * The static functions are basically wrappers around the C implementation,
+ * using UnicodeString instead of UChar*.
+ * For basic information about normalization forms and details about the C API
+ * please see the documentation in unorm.h.
+ *
+ * The iterator API with the Normalizer constructors and the non-static functions
+ * uses a CharacterIterator as input. It is possible to pass a string which
+ * is then internally wrapped in a CharacterIterator.
+ * The input text is not normalized all at once, but incrementally where needed
+ * (providing efficient random access).
+ * This allows to pass in a large text but spend only a small amount of time
+ * normalizing a small part of that text.
+ * However, if the entire text is normalized, then the iterator will be
+ * slower than normalizing the entire text at once and iterating over the result.
+ * A possible use of the Normalizer iterator is also to report an index into the
+ * original text that is close to where the normalized characters come from.
+ *
+ * <em>Important:</em> The iterator API was cleaned up significantly for ICU 2.0.
+ * The earlier implementation reported the getIndex() inconsistently,
+ * and previous() could not be used after setIndex(), next(), first(), and current().
+ *
+ * Normalizer allows to start normalizing from anywhere in the input text by
+ * calling setIndexOnly(), first(), or last().
+ * Without calling any of these, the iterator will start at the beginning of the text.
+ *
+ * At any time, next() returns the next normalized code point (UChar32),
+ * with post-increment semantics (like CharacterIterator::next32PostInc()).
+ * previous() returns the previous normalized code point (UChar32),
+ * with pre-decrement semantics (like CharacterIterator::previous32()).
+ *
+ * current() returns the current code point
+ * (respectively the one at the newly set index) without moving
+ * the getIndex(). Note that if the text at the current position
+ * needs to be normalized, then these functions will do that.
+ * (This is why current() is not const.)
+ * It is more efficient to call setIndexOnly() instead, which does not
+ * normalize.
+ *
+ * getIndex() always refers to the position in the input text where the normalized
+ * code points are returned from. It does not always change with each returned
+ * code point.
+ * The code point that is returned from any of the functions
+ * corresponds to text at or after getIndex(), according to the
+ * function's iteration semantics (post-increment or pre-decrement).
+ *
+ * next() returns a code point from at or after the getIndex()
+ * from before the next() call. After the next() call, the getIndex()
+ * might have moved to where the next code point will be returned from
+ * (from a next() or current() call).
+ * This is semantically equivalent to array access with array[index++]
+ * (post-increment semantics).
+ *
+ * previous() returns a code point from at or after the getIndex()
+ * from after the previous() call.
+ * This is semantically equivalent to array access with array[--index]
+ * (pre-decrement semantics).
+ *
+ * Internally, the Normalizer iterator normalizes a small piece of text
+ * starting at the getIndex() and ending at a following "safe" index.
+ * The normalized results is stored in an internal string buffer, and
+ * the code points are iterated from there.
+ * With multiple iteration calls, this is repeated until the next piece
+ * of text needs to be normalized, and the getIndex() needs to be moved.
+ *
+ * The following "safe" index, the internal buffer, and the secondary
+ * iteration index into that buffer are not exposed on the API.
+ * This also means that it is currently not practical to return to
+ * a particular, arbitrary position in the text because one would need to
+ * know, and be able to set, in addition to the getIndex(), at least also the
+ * current index into the internal buffer.
+ * It is currently only possible to observe when getIndex() changes
+ * (with careful consideration of the iteration semantics),
+ * at which time the internal index will be 0.
+ * For example, if getIndex() is different after next() than before it,
+ * then the internal index is 0 and one can return to this getIndex()
+ * later with setIndexOnly().

+/**
+ * <code>Replaceable</code> is an abstract base class representing a
+ * string of characters that supports the replacement of a range of
+ * itself with a new string of characters.  It is used by APIs that
+ * change a piece of text while retaining metadata.  Metadata is data
+ * other than the Unicode characters returned by char32At().  One
+ * example of metadata is style attributes; another is an edit
+ * history, marking each character with an author and revision number.
+ *
+ * <p>An implicit aspect of the <code>Replaceable</code> API is that
+ * during a replace operation, new characters take on the metadata of
+ * the old characters.  For example, if the string "the <b>bold</b>
+ * font" has range (4, 8) replaced with "strong", then it becomes "the
+ * <b>strong</b> font".
+ *
+ * <p><code>Replaceable</code> specifies ranges using a start
+ * offset and a limit offset.  The range of characters thus specified
+ * includes the characters at offset start..limit-1.  That is, the
+ * start offset is inclusive, and the limit offset is exclusive.
+ *
+ * <p><code>Replaceable</code> also includes API to access characters
+ * in the string: <code>length()</code>, <code>charAt()</code>,
+ * <code>char32At()</code>, and <code>extractBetween()</code>.
+ *
+ * <p>For a subclass to support metadata, typical behavior of
+ * <code>replace()</code> is the following:
+ * <ul>
+ *   <li>Set the metadata of the new text to the metadata of the first
+ *   character replaced</li>
+ *   <li>If no characters are replaced, use the metadata of the
+ *   previous character</li>
+ *   <li>If there is no previous character (i.e. start == 0), use the
+ *   following character</li>
+ *   <li>If there is no following character (i.e. the replaceable was
+ *   empty), use default metadata.<br>
+ *   <li>If the code point U+FFFF is seen, it should be interpreted as
+ *   a special marker having no metadata<li>
+ *   </li>
+ * </ul>
+ * If this is not the behavior, the subclass should document any differences.

+*   Date        Name        Description
+*   2/5/97      aliu        Added scanForLocaleInFile.  Added
+*                           constructor which attempts to read resource bundle
+*                           from a specific file, without searching other files.
+*   2/11/97     aliu        Added UErrorCode return values to constructors.  Fixed
+*                           infinite loops in scanForFile and scanForLocale.
+*                           Modified getRawResourceData to not delete storage
+*                           in localeData and resourceData which it doesn't own.
+*                           Added Mac compatibility #ifdefs for tellp() and
+*                           ios::nocreate.
+*   2/18/97     helena      Updated with 100% documentation coverage.
+*   3/13/97     aliu        Rewrote to load in entire resource bundle and store
+*                           it as a Hashtable of ResourceBundleData objects.
+*                           Added state table to govern parsing of files.
+*                           Modified to load locale index out of new file
+*                           distinct from default.txt.
+*   3/25/97     aliu        Modified to support 2-d arrays, needed for timezone
+*                           data. Added support for custom file suffixes.  Again,
+*                           needed to support timezone data.
+*   4/7/97      aliu        Cleaned up.

+ * UnicodeString*.  The type you get is determine by the variant of
+ * 'next' that you call.  In general the StringEnumeration is
+ * optimized for one of these types, but all StringEnumerations can
+ * return all types.  Returned strings are each terminated with a NUL.
+ * Depending on the service data, they might also include embedded NUL
+ * characters, so API is provided to optionally return the true

+ * names.  All symbolic names start with the SYMBOL_REF character.

+/**
+ *\file
+ * \brief C API: BIDI algorithm
+ *
+ * <h2>BIDI algorithm for ICU</h2>
+ *
+ * This is an implementation of the Unicode Bidirectional algorithm.
+ * The algorithm is defined in the
+ * <a href="http://www.unicode.org/unicode/reports/tr9/">Unicode Standard Annex #9</a>,
+ * version 13, also described in The Unicode Standard, Version 4.0 .<p>
+ *
+ * Note: Libraries that perform a bidirectional algorithm and
+ * reorder strings accordingly are sometimes called "Storage Layout Engines".
+ * ICU's BiDi and shaping (u_shapeArabic()) APIs can be used at the core of such
+ * "Storage Layout Engines".
+ *
+ * <h3>General remarks about the API:</h3>
+ *
+ * In functions with an error code parameter,
+ * the <code>pErrorCode</code> pointer must be valid
+ * and the value that it points to must not indicate a failure before
+ * the function call. Otherwise, the function returns immediately.
+ * After the function call, the value indicates success or failure.<p>
+ *
+ * The &quot;limit&quot; of a sequence of characters is the position just after their
+ * last character, i.e., one more than that position.<p>
+ *
+ * Some of the API functions provide access to &quot;runs&quot;.
+ * Such a &quot;run&quot; is defined as a sequence of characters
+ * that are at the same embedding level
+ * after performing the BIDI algorithm.<p>
+ *
+ * @author Markus W. Scherer

+ * <h4> Sample code for the ICU BIDI API </h4>
+ *
+ * <h5>Rendering a paragraph with the ICU BiDi API</h5>
+ *
+ * This is (hypothetical) sample code that illustrates
+ * how the ICU BiDi API could be used to render a paragraph of text.
+ * Rendering code depends highly on the graphics system,
+ * therefore this sample code must make a lot of assumptions,
+ * which may or may not match any existing graphics system's properties.
+ *
+ * <p>The basic assumptions are:</p>
+ * <ul>
+ * <li>Rendering is done from left to right on a horizontal line.</li>
+ * <li>A run of single-style, unidirectional text can be rendered at once.</li>
+ * <li>Such a run of text is passed to the graphics system with
+ *     characters (code units) in logical order.</li>
+ * <li>The line-breaking algorithm is very complicated
+ *     and Locale-dependent -
+ *     and therefore its implementation omitted from this sample code.</li>
+ * </ul>

+ *
+ * <p>In other cases, it may be desirable to emulate some variant of the
+ * Logical to Visual algorithm (e.g. one used in MS Windows), or perform a
+ * Logical to Logical transformation.</p>
+ *
+ * <ul>
+ * <li>When the reordering mode is set to <code>#UBIDI_REORDER_DEFAULT</code>,
+ * the standard BiDi Logical to Visual algorithm is applied.</li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_NUMBERS_SPECIAL</code>,
+ * the algorithm used to perform BiDi transformations when calling
+ * <code>ubidi_setPara</code> should approximate the algorithm used in
+ * Microsoft Windows XP rather than strictly conform to the Unicode BiDi
+ * algorithm.
+ * <br>
+ * The differences between the basic algorithm and the algorithm addressed
+ * by this option are as follows:
+ * <ul>
+ *   <li>Within text at an even embedding level, the sequence "123AB"
+ *   (where AB represent R or AL letters) is transformed to "123BA" by the
+ *   Unicode algorithm and to "BA123" by the Windows algorithm.</li>
+ *   <li>Arabic-Indic numbers (AN) are handled by the Windows algorithm just
+ *   like regular numbers (EN).</li>
+ * </ul></li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_GROUP_NUMBERS_WITH_R</code>,
+ * numbers located between LTR text and RTL text are associated with the RTL
+ * text. For instance, an LTR paragraph with content "abc 123 DEF" (where
+ * upper case letters represent RTL characters) will be transformed to
+ * "abc FED 123" (and not "abc 123 FED"), "DEF 123 abc" will be transformed
+ * to "123 FED abc" and "123 FED abc" will be transformed to "DEF 123 abc".
+ * This makes the algorithm reversible and makes it useful when round trip
+ * (from visual to logical and back to visual) must be achieved without
+ * adding LRM characters. However, this is a variation from the standard
+ * Unicode Bidi algorithm.<br>
+ * The source text should not contain BiDi control characters other than LRM
+ * or RLM.</li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_RUNS_ONLY</code>,
+ * a "Logical to Logical" transformation must be performed:
+ * <ul>
+ * <li>If the default text level of the source text (argument <code>paraLevel</code>
+ * in <code>ubidi_setPara</code>) is even, the source text will be handled as
+ * LTR logical text and will be transformed to the RTL logical text which has
+ * the same LTR visual display.</li>
+ * <li>If the default level of the source text is odd, the source text
+ * will be handled as RTL logical text and will be transformed to the
+ * LTR logical text which has the same LTR visual display.</li>
+ * </ul>
+ * This mode may be needed when logical text which is basically Arabic or
+ * Hebrew, with possible included numbers or phrases in English, has to be
+ * displayed as if it had an even embedding level (this can happen if the
+ * displaying application treats all text as if it was basically LTR.
+ * <br>
+ * This mode may also be needed in the reverse case, when logical text which is
+ * basically English, with possible included phrases in Arabic or Hebrew, has to
+ * be displayed as if it had an odd embedding level.
+ * <br>
+ * Both cases could be handled by adding LRE or RLE at the head of the text,
+ * if the display subsystem supports these formatting controls. If it does not,
+ * the problem may be handled by transforming the source text in this mode
+ * before displaying it, so that it will be displayed properly.<br>
+ * The source text should not contain BiDi control characters other than LRM
+ * or RLM.</li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>, an "inverse BiDi" algorithm
+ * is applied.
+ * Runs of text with numeric characters will be treated like LTR letters and

+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_INVERSE_LIKE_DIRECT</code>, the "direct" Logical to Visual
+ * BiDi algorithm is used as an approximation of an "inverse BiDi" algorithm.
+ * This mode is similar to mode <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>
+ * but is closer to the regular BiDi algorithm.
+ * <br>
+ * For example, an LTR paragraph with the content "FED 123 456 CBA" (where
+ * upper case represents RTL characters) will be transformed to
+ * "ABC 456 123 DEF", as opposed to "DEF 123 456 ABC"
+ * with mode <code>UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>.<br>
+ * When used in conjunction with option
+ * <code>#UBIDI_OPTION_INSERT_MARKS</code>, this mode generally
+ * adds BiDi marks to the output significantly more sparingly than mode
+ * <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code> with option
+ * <code>#UBIDI_INSERT_LRM_FOR_NUMERIC</code> in calls to
+ * <code>ubidi_writeReordered</code>.</li>
+ *
+ * <li>When the reordering mode is set to
+ * <code>#UBIDI_REORDER_INVERSE_FOR_NUMBERS_SPECIAL</code>, the Logical to Visual
+ * BiDi algorithm used in Windows XP is used as an approximation of an
+ * "inverse BiDi" algorithm.
+ * <br>
+ * For example, an LTR paragraph with the content "abc FED123" (where

+ *
+ * <p>In all the reordering modes specifying an "inverse BiDi" algorithm

+/**
+ * Perform the Unicode BiDi algorithm. It is defined in the
+ * <a href="http://www.unicode.org/unicode/reports/tr9/">Unicode Standard Anned #9</a>,
+ * version 13,
+ * also described in The Unicode Standard, Version 4.0 .<p>
+ *
+ * This function takes a piece of plain text containing one or more paragraphs,
+ * with or without externally specified embedding levels from <i>styled</i>
+ * text and computes the left-right-directionality of each character.<p>
+ *
+ * If the entire text is all of the same directionality, then
+ * the function may not perform all the steps described by the algorithm,
+ * i.e., some levels may not be the same as if all steps were performed.
+ * This is not relevant for unidirectional text.<br>
+ * For example, in pure LTR text with numbers the numbers would get
+ * a resolved level of 2 higher than the surrounding text according to
+ * the algorithm. This implementation may set all resolved levels to
+ * the same value in such a case.<p>
+ *
+ * The text can be composed of multiple paragraphs. Occurrence of a block
+ * separator in the text terminates a paragraph, and whatever comes next starts
+ * a new paragraph. The exception to this rule is when a Carriage Return (CR)
+ * is followed by a Line Feed (LF). Both CR and LF are block separators, but
+ * in that case, the pair of characters is considered as terminating the
+ * preceding paragraph, and a new paragraph will be started by a character
+ * coming after the LF.
+ *
+ * @param pBiDi A <code>UBiDi</code> object allocated with <code>ubidi_open()</code>
+ *        which will be set to contain the reordering information,
+ *        especially the resolved levels for all the characters in <code>text</code>.
+ *
+ * @param text is a pointer to the text that the BiDi algorithm will be performed on.
+ *        This pointer is stored in the UBiDi object and can be retrieved
+ *        with <code>ubidi_getText()</code>.<br>
+ *        <strong>Note:</strong> the text must be (at least) <code>length</code> long.
+ *
+ * @param length is the length of the text; if <code>length==-1</code> then
+ *        the text must be zero-terminated.
+ *
+ * @param paraLevel specifies the default level for the text;
+ *        it is typically 0 (LTR) or 1 (RTL).
+ *        If the function shall determine the paragraph level from the text,
+ *        then <code>paraLevel</code> can be set to
+ *        either <code>#UBIDI_DEFAULT_LTR</code>
+ *        or <code>#UBIDI_DEFAULT_RTL</code>; if the text contains multiple
+ *        paragraphs, the paragraph level shall be determined separately for
+ *        each paragraph; if a paragraph does not include any strongly typed
+ *        character, then the desired default is used (0 for LTR or 1 for RTL).
+ *        Any other value between 0 and <code>#UBIDI_MAX_EXPLICIT_LEVEL</code>
+ *        is also valid, with odd levels indicating RTL.
+ *
+ * @param embeddingLevels (in) may be used to preset the embedding and override levels,
+ *        ignoring characters like LRE and PDF in the text.
+ *        A level overrides the directional property of its corresponding
+ *        (same index) character if the level has the
+ *        <code>#UBIDI_LEVEL_OVERRIDE</code> bit set.<br><br>
+ *        Except for that bit, it must be
+ *        <code>paraLevel<=embeddingLevels[]<=UBIDI_MAX_EXPLICIT_LEVEL</code>,
+ *        with one exception: a level of zero may be specified for a paragraph
+ *        separator even if <code>paraLevel>0</code> when multiple paragraphs
+ *        are submitted in the same call to <code>ubidi_setPara()</code>.<br><br>
+ *        <strong>Caution: </strong>A copy of this pointer, not of the levels,
+ *        will be stored in the <code>UBiDi</code> object;
+ *        the <code>embeddingLevels</code> array must not be
+ *        deallocated before the <code>UBiDi</code> structure is destroyed or reused,
+ *        and the <code>embeddingLevels</code>
+ *        should not be modified to avoid unexpected results on subsequent BiDi operations.
+ *        However, the <code>ubidi_setPara()</code> and

+ * \brief C API: BreakIterator
+ *
+ * <h2> BreakIterator C API </h2>
+ *
+ * The BreakIterator C API defines  methods for finding the location
+ * of boundaries in text. Pointer to a UBreakIterator maintain a
+ * current position and scan over text returning the index of characters
+ * where boundaries occur.
+ * <p>
+ * Line boundary analysis determines where a text string can be broken
+ * when line-wrapping. The mechanism correctly handles punctuation and
+ * hyphenated words.
+ * <p>
+ * Sentence boundary analysis allows selection with correct
+ * interpretation of periods within numbers and abbreviations, and
+ * trailing punctuation marks such as quotation marks and parentheses.
+ * <p>
+ * Word boundary analysis is used by search and replace functions, as
+ * well as within text editing applications that allow the user to
+ * select words with a double click. Word selection provides correct
+ * interpretation of punctuation marks within and following
+ * words. Characters that are not part of a word, such as symbols or
+ * punctuation marks, have word-breaks on both sides.
+ * <p>
+ * Character boundary analysis allows users to interact with
+ * characters as they expect to, for example, when moving the cursor
+ * through a text string. Character boundary analysis provides correct
+ * navigation of through character strings, regardless of how the
+ * character is stored.  For example, an accented character might be
+ * stored as a base character and a diacritical mark. What users
+ * consider to be a character can differ between languages.
+ * <p>
+ * Title boundary analysis locates all positions,
+ * typically starts of words, that should be set to Title Case
+ * when title casing the text.
+ * <p>
+ * The text boundary positions are found according to the rules
+ * described in Unicode Standard Annex #29, Text Boundaries, and

+/**
+ * \file
+ * \brief C API: Message Catalog Wrappers
+ *
+ * This C API provides look-alike functions that deliberately resemble
+ * the POSIX catopen, catclose, and catgets functions.  The underlying
+ * implementation is in terms of ICU resource bundles, rather than
+ * POSIX message catalogs.
+ *
+ * The ICU resource bundles obey standard ICU inheritance policies.
+ * To facilitate this, sets and messages are flattened into one tier.
+ * This is done by creating resource bundle keys of the form
+ * &lt;set_num&gt;%&lt;msg_num&gt; where set_num is the set number and msg_num is
+ * the message number, formatted as decimal strings.
+ *
+ * Example:  Consider a message catalog containing two sets:
+ *
+ * Set 1: Message 4  = "Good morning."
+ *        Message 5  = "Good afternoon."
+ *        Message 7  = "Good evening."
+ *        Message 8  = "Good night."
+ * Set 4: Message 14 = "Please "
+ *        Message 19 = "Thank you."
+ *        Message 20 = "Sincerely,"
+ *
+ * The ICU resource bundle source file would, assuming it is named
+ * "greet.txt", would look like this:
+ *
+ * greet
+ * {
+ *     1%4  { "Good morning." }
+ *     1%5  { "Good afternoon." }
+ *     1%7  { "Good evening." }
+ *     1%8  { "Good night." }
+ * 
+ *     4%14 { "Please " }
+ *     4%19 { "Thank you." }
+ *     4%20 { "Sincerely," }
+ * }
+ *
+ * The catgets function is commonly used in combination with functions
+ * like printf and strftime.  ICU components like message format can
+ * be used instead, although they use a different format syntax.
+ * There is an ICU package, icuio, that provides some of
+ * the POSIX-style formatting API.

+/**
+ * \file
+ * \brief C API: Unicode Properties
+ *
+ * This C API provides low-level access to the Unicode Character Database.
+ * In addition to raw property values, some convenience functions calculate
+ * derived properties, for example for Java-style programming.
+ *
+ * Unicode assigns each code point (not just assigned character) values for
+ * many properties.
+ * Most of them are simple boolean flags, or constants from a small enumerated list.
+ * For some properties, values are strings or other relatively more complex types.
+ *
+ * For more information see
+ * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
+ * and the ICU User Guide chapter on Properties (http://icu.sourceforge.net/userguide/properties.html).
+ *
+ * Many functions are designed to match java.lang.Character functions.
+ * See the individual function documentation,
+ * and see the JDK 1.4 java.lang.Character documentation
+ * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
+ *
+ * There are also functions that provide easy migration from C/POSIX functions
+ * like isblank(). Their use is generally discouraged because the C/POSIX
+ * standards do not define their semantics beyond the ASCII range, which means
+ * that different implementations exhibit very different behavior.
+ * Instead, Unicode properties should be used directly.
+ *
+ * There are also only a few, broad C/POSIX character classes, and they tend
+ * to be used for conflicting purposes. For example, the "isalpha()" class
+ * is sometimes used to determine word boundaries, while a more sophisticated
+ * approach would at least distinguish initial letters from continuation
+ * characters (the latter including combining marks).
+ * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
+ * Another example: There is no "istitle()" class for titlecase characters.
+ *
+ * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
+ * ICU implements them according to the Standard Recommendations in
+ * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
+ * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).
+ *
+ * API access for C/POSIX character classes is as follows:
+ * - alpha:     u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
+ * - lower:     u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
+ * - upper:     u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
+ * - punct:     u_ispunct(c)
+ * - digit:     u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
+ * - xdigit:    u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
+ * - alnum:     u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
+ * - space:     u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
+ * - blank:     u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
+ * - cntrl:     u_charType(c)==U_CONTROL_CHAR
+ * - graph:     u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
+ * - print:     u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
+ *
+ * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
+ * the Standard Recommendations in UTS #18. Instead, they match Java
+ * functions according to their API documentation.
+ *
+ * \htmlonly
+ * The C/POSIX character classes are also available in UnicodeSet patterns,
+ * using patterns like [:graph:] or \p{graph}.
+ * \endhtmlonly
+ *
+ * Note: There are several ICU whitespace functions.
+ * Comparison:
+ * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
+ *       most of general categories "Z" (separators) + most whitespace ISO controls
+ *       (including no-break spaces, but excluding IS1..IS4 and ZWSP)
+ * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
+ * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
+ * - u_isspace: Z + whitespace ISO controls (including no-break spaces)

+        These properties are computed as follows - an inert character is:
+        a) unassigned, or ALL of the following:
+        b) of combining class 0.
+        c) not decomposed by this normalization form.
+        AND if NFC or NFKC,
+        d) can never compose with a previous character.
+        e) can never compose with a following character.
+        f) can never change if another character is added.
+           Example: a-breve might satisfy all but f, but if you
+           add an ogonek it changes to a-ogonek + breve

+/**
+ *  Initialize ICU. The description further below applies to ICU 2.6 to ICU 3.4.
+ *  Starting with ICU 3.4, u_init() needs not be called any more for
+ *  ensuring thread safety, but it can give an indication for whether ICU
+ *  can load its data. In ICU 3.4, it will try to load the converter alias table
+ *  (cnvalias.icu) and give an error code if that fails.
+ *  This may change in the future.
+ *  <p>
+ *  For ensuring the availability of necessary data, an application should
+ *  open the service objects (converters, collators, etc.) that it will use
+ *  and check for error codes there.
+ *  <p>
+ *  Documentation for ICU 2.6 to ICU 3.4:
+ *  <p>
+ *  This function loads and initializes data items
+ *  that are required internally by various ICU functions.  Use of this explicit
+ *  initialization is required in multi-threaded applications; in 
+ *  single threaded apps, use is optional, but incurs little additional
+ *  cost, and is thus recommended.
+ *  <p>
+ *  In multi-threaded applications, u_init() should be called  in the
+ *  main thread before starting additional threads, or, alternatively
+ *  it can be called in each individual thread once, before other ICU
+ *  functions are called in that thread.  In this second scenario, the
+ *  application must guarantee that the first call to u_init() happen
+ *  without contention, in a single thread only.
+ *  <p>
+ *  If <code>u_setMemoryFunctions()</code> or 
+ *  <code>u_setMutexFunctions</code> are needed (uncommon), they must be
+ *  called _before_ <code>u_init()</code>.
+ *  <p>
+ *  Extra, repeated, or otherwise unneeded calls to u_init() do no harm,
+ *  other than taking a small amount of time.
+ *
+ * @param status An ICU UErrorCode parameter. It must not be <code>NULL</code>.
+ *    An Error will be returned if some required part of ICU data can not
+ *    be loaded or initialized.
+ *    The function returns immediately if the input error code indicates a
+ *    failure, as usual.

+/**
+ * Clean up the system resources, such as allocated memory or open files,
+ * used in all ICU libraries. This will free/delete all memory owned by the
+ * ICU libraries, and return them to their original load state. All open ICU
+ * items (collators, resource bundles, converters, etc.) must be closed before
+ * calling this function, otherwise ICU may not free its allocated memory
+ * (e.g. close your converters and resource bundles before calling this
+ * function). Generally, this function should be called once just before
+ * an application exits. For applications that dynamically load and unload
+ * the ICU libraries (relatively uncommon), u_cleanup() should be called
+ * just before the library unload.
+ * <p>
+ * u_cleanup() also clears any ICU heap functions, mutex functions or
+ * trace functions that may have been set for the process.  
+ * This has the effect of restoring ICU to its initial condition, before
+ * any of these override functions were installed.  Refer to
+ * u_setMemoryFunctions(), u_setMutexFunctions and 
+ * utrace_setFunctions().  If ICU is to be reinitialized after after
+ * calling u_cleanup(), these runtime override functions will need to
+ * be set up again if they are still required.
+ * <p>
+ * u_cleanup() is not thread safe.  All other threads should stop using ICU
+ * before calling this function.
+ * <p>
+ * Any open ICU items will be left in an undefined state by u_cleanup(),
+ * and any subsequent attempt to use such an item will give unpredictable
+ * results.
+ * <p>
+ * After calling u_cleanup(), an application may continue to use ICU by
+ * calling u_init().  An application must invoke u_init() first from one single
+ * thread before allowing other threads call u_init().  All threads existing
+ * at the time of the first thread's call to u_init() must also call
+ * u_init() themselves before continuing with other ICU operations.  
+ * <p>
+ * The use of u_cleanup() just before an application terminates is optional,
+ * but it should be called only once for performance reasons. The primary
+ * benefit is to eliminate reports of memory or resource leaks originating
+ * in ICU code from the results generated by heap analysis tools.

+ * \brief C API: Character conversion 
+ *
+ * <h2>Character Conversion C API</h2>
+ *
+ * <p>This API is used to convert codepage or character encoded data to and
+ * from UTF-16. You can open a converter with {@link ucnv_open() }. With that
+ * converter, you can get its properties, set options, convert your data and
+ * close the converter.</p>
+ *
+ * <p>Since many software programs recogize different converter names for
+ * different types of converters, there are other functions in this API to
+ * iterate over the converter aliases. The functions {@link ucnv_getAvailableName() },
+ * {@link ucnv_getAlias() } and {@link ucnv_getStandardName() } are some of the
+ * more frequently used alias functions to get this information.</p>
+ *
+ * <p>When a converter encounters an illegal, irregular, invalid or unmappable character
+ * its default behavior is to use a substitution character to replace the
+ * bad byte sequence. This behavior can be changed by using {@link ucnv_setFromUCallBack() }
+ * or {@link ucnv_setToUCallBack() } on the converter. The header ucnv_err.h defines
+ * many other callback actions that can be used instead of a character substitution.</p>
+ *
+ * <p>More information about this API can be found in our 
+ * <a href="http://icu.sourceforge.net/userguide/conversion.html">User's
+ * Guide</a>.</p>

+ * The input is completely consumed when the U_INDEX_OUTOFBOUNDS_ERROR is set.
+ *
+ * Advantage compared to ucnv_toUnicode() or ucnv_toUChars():
+ * - Faster for small amounts of data, for most converters, e.g.,
+ *   US-ASCII, ISO-8859-1, UTF-8/16/32, and most "normal" charsets.
+ *   (For complex converters, e.g., SCSU, UTF-7 and ISO 2022 variants,
+ *    it uses ucnv_toUnicode() internally.)
+ * - Convenient.
+ *
+ * Limitations compared to ucnv_toUnicode():
+ * - Always assumes flush=TRUE.
+ *   This makes ucnv_getNextUChar() unsuitable for "streaming" conversion,
+ *   that is, for where the input is supplied in multiple buffers,
+ *   because ucnv_getNextUChar() will assume the end of the input at the end
+ *   of the first buffer.
+ * - Does not provide offset output.
+ *
+ * It is possible to "mix" ucnv_getNextUChar() and ucnv_toUnicode() because
+ * ucnv_getNextUChar() uses the current state of the converter
+ * (unlike ucnv_toUChars() which always resets first).
+ * However, if ucnv_getNextUChar() is called after ucnv_toUnicode()
+ * stopped in the middle of a character sequence (with flush=FALSE),
+ * then ucnv_getNextUChar() will always use the slower ucnv_toUnicode()
+ * internally until the next character boundary.
+ * (This is new in ICU 2.6. In earlier releases, ucnv_getNextUChar() had to
+ * start at a character boundary.)
+ *
+ * Instead of using ucnv_getNextUChar(), it is recommended
+ * to convert using ucnv_toUnicode() or ucnv_toUChars()
+ * and then iterate over the text using U16_NEXT() or a UCharIterator (uiter.h)
+ * or a C++ CharacterIterator or similar.
+ * This allows streaming conversion and offset output, for example.
+ *
+ * <p>Handling of surrogate pairs and supplementary-plane code points:<br>
+ * There are two different kinds of codepages that provide mappings for surrogate characters:
+ * <ul>
+ *   <li>Codepages like UTF-8, UTF-32, and GB 18030 provide direct representations for Unicode
+ *       code points U+10000-U+10ffff as well as for single surrogates U+d800-U+dfff.
+ *       Each valid sequence will result in exactly one returned code point.
+ *       If a sequence results in a single surrogate, then that will be returned
+ *       by itself, even if a neighboring sequence encodes the matching surrogate.</li>
+ *   <li>Codepages like SCSU and LMBCS (and UTF-16) provide direct representations only for BMP code points
+ *       including surrogates. Code points in supplementary planes are represented with
+ *       two sequences, each encoding a surrogate.
+ *       For these codepages, matching pairs of surrogates will be combined into single
+ *       code points for returning from this function.
+ *       (Note that SCSU is actually a mix of these codepage types.)</li>
+ * </ul></p>
+ *
+ * @param converter an open UConverter
+ * @param source the address of a pointer to the codepage buffer, will be
+ *  updated to point after the bytes consumed in the conversion call.
+ * @param sourceLimit points to the end of the input buffer
+ * @param err fills in error status (see ucnv_toUnicode)
+ * <code>U_INDEX_OUTOFBOUNDS_ERROR</code> will be set if the input 
+ * is empty or does not convert to any output (e.g.: pure state-change 
+ * codes SI/SO, escape sequences for ISO 2022,

+ * Convert from one external charset to another using two existing UConverters.
+ * Internally, two conversions - ucnv_toUnicode() and ucnv_fromUnicode() -
+ * are used, "pivoting" through 16-bit Unicode.
+ *
+ * Important: For streaming conversion (multiple function calls for successive
+ * parts of a text stream), the caller must provide a pivot buffer explicitly,
+ * and must preserve the pivot buffer and associated pointers from one
+ * call to another. (The buffer may be moved if its contents and the relative
+ * pointer positions are preserved.)
+ *
+ * There is a similar function, ucnv_convert(),
+ * which has the following limitations:
+ * - it takes charset names, not converter objects, so that
+ *   - two converters are opened for each call
+ *   - only single-string conversion is possible, not streaming operation
+ * - it does not provide enough information to find out,
+ *   in case of failure, whether the toUnicode or
+ *   the fromUnicode conversion failed
+ *
+ * By contrast, ucnv_convertEx()
+ * - takes UConverter parameters instead of charset names
+ * - fully exposes the pivot buffer for streaming conversion and complete error handling
+ *
+ * ucnv_convertEx() also provides further convenience:
+ * - an option to reset the converters at the beginning
+ *   (if reset==TRUE, see parameters;
+ *    also sets *pivotTarget=*pivotSource=pivotStart)
+ * - allow NUL-terminated input
+ *   (only a single NUL byte, will not work for charsets with multi-byte NULs)
+ *   (if sourceLimit==NULL, see parameters)
+ * - terminate with a NUL on output
+ *   (only a single NUL byte, not useful for charsets with multi-byte NULs),
+ *   or set U_STRING_NOT_TERMINATED_WARNING if the output exactly fills
+ *   the target buffer
+ * - the pivot buffer can be provided internally;
+ *   possible only for whole-string conversion, not streaming conversion;
+ *   in this case, the caller will not be able to get details about where an
+ *   error occurred
+ *   (if pivotStart==NULL, see below)
+ *
+ * The function returns when one of the following is true:
+ * - the entire source text has been converted successfully to the target buffer
+ * - a target buffer overflow occurred (U_BUFFER_OVERFLOW_ERROR)
+ * - a conversion error occurred
+ *   (other U_FAILURE(), see description of pErrorCode)
+ *
+ * Limitation compared to the direct use of
+ * ucnv_fromUnicode() and ucnv_toUnicode():
+ * ucnv_convertEx() does not provide offset information.
+ *
+ * Limitation compared to ucnv_fromUChars() and ucnv_toUChars():
+ * ucnv_convertEx() does not support preflighting directly.

+ * one external charset to UTF-8, ignoring the location of errors:

+ * see ucnv_err.h.  DO NOT call these functions directly when you are 
+ * working with converters, unless your code has been called as a callback
+ * via ucnv_setFromUCallback or ucnv_setToUCallback !!
+ * 
+ * A note about error codes and overflow.  Unlike other ICU functions,
+ * these functions do not expect the error status to be U_ZERO_ERROR.
+ * Callbacks must be much more careful about their error codes.
+ * The error codes used here are in/out parameters, which should be passed
+ * back in the callback's error parameter.
+ * 
+ * For example, if you call ucnv_cbfromUWriteBytes to write data out 
+ * to the output codepage, it may return U_BUFFER_OVERFLOW_ERROR if 
+ * the data did not fit in the target. But this isn't a failing error, 
+ * in fact, ucnv_cbfromUWriteBytes may be called AGAIN with the error
+ * status still U_BUFFER_OVERFLOW_ERROR to attempt to write further bytes,
+ * which will also go into the internal overflow buffers.
+ * 
+ * Concerning offsets, the 'offset' parameters here are relative to the start
+ * of SOURCE.  For example, Suppose the string "ABCD" was being converted 
+ * from Unicode into a codepage which doesn't have a mapping for 'B'.
+ * 'A' will be written out correctly, but
+ * The FromU Callback will be called on an unassigned character for 'B'.
+ * At this point, this is the state of the world:
+ *    Target:    A [..]     [points after A]
+ *    Source:  A B [C] D    [points to C - B has been consumed]
+ *             0 1  2  3 
+ *    codePoint = "B"       [the unassigned codepoint] 
+ * 
+ * Now, suppose a callback wants to write the substitution character '?' to
+ * the target. It calls ucnv_cbFromUWriteBytes() to write the ?. 
+ * It should pass ZERO as the offset, because the offset as far as the 
+ * callback is concerned is relative to the SOURCE pointer [which points 
+ * before 'C'.]  If the callback goes into the args and consumes 'C' also,
+ * it would call FromUWriteBytes with an offset of 1 (and advance the source
+ * pointer).

+/**
+ * \file
+ * \brief C UConverter predefined error callbacks
+ *
+ *  <h2>Error Behaviour Functions</h2>
+ *  Defines some error behaviour functions called by ucnv_{from,to}Unicode
+ *  These are provided as part of ICU and many are stable, but they
+ *  can also be considered only as an example of what can be done with
+ *  callbacks.  You may of course write your own.
+ *
+ *  If you want to write your own, you may also find the functions from
+ *  ucnv_cb.h useful when writing your own callbacks.
+ *
+ *  These functions, although public, should NEVER be called directly.
+ *  They should be used as parameters to the ucnv_setFromUCallback
+ *  and ucnv_setToUCallback functions, to set the behaviour of a converter
+ *  when it encounters ILLEGAL/UNMAPPED/INVALID sequences.
+ *
+ *  usage example:  'STOP' doesn't need any context, but newContext
+ *    could be set to something other than 'NULL' if needed. The available
+ *    contexts in this header can modify the default behavior of the callback.
+ *
+ *  \code
+ *  UErrorCode err = U_ZERO_ERROR;
+ *  UConverter *myConverter = ucnv_open("ibm-949", &err);
+ *  const void *oldContext;
+ *  UConverterFromUCallback oldAction;
+ *
+ *
+ *  if (U_SUCCESS(err))
+ *  {
+ *      ucnv_setFromUCallBack(myConverter,
+ *                       UCNV_FROM_U_CALLBACK_STOP,
+ *                       NULL,
+ *                       &oldAction,
+ *                       &oldContext,
+ *                       &status);
+ *  }
+ *  \endcode
+ *
+ *  The code above tells "myConverter" to stop when it encounters an
+ *  ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
+ *  Unicode -> Codepage. The behavior from Codepage to Unicode is not changed,
+ *  and ucnv_setToUCallBack would need to be called in order to change
+ *  that behavior too.
+ *
+ *  Here is an example with a context:
+ *
+ *  \code
+ *  UErrorCode err = U_ZERO_ERROR;
+ *  UConverter *myConverter = ucnv_open("ibm-949", &err);
+ *  const void *oldContext;
+ *  UConverterFromUCallback oldAction;
+ *
+ *
+ *  if (U_SUCCESS(err))
+ *  {
+ *      ucnv_setToUCallBack(myConverter,
+ *                       UCNV_TO_U_CALLBACK_SUBSTITUTE,
+ *                       UCNV_SUB_STOP_ON_ILLEGAL,
+ *                       &oldAction,
+ *                       &oldContext,
+ *                       &status);
+ *  }
+ *  \endcode
+ *
+ *  The code above tells "myConverter" to stop when it encounters an
+ *  ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
+ *  Codepage -> Unicode. Any unmapped and legal characters will be
+ *  substituted to be the default substitution character.

+ * <p>The implementation depends on platform properties and user preferences
+ * and may involve loading shared libraries (DLLs), mapping
+ * files into memory, or fopen()/fread() files.
+ * It may also involve using static memory or database queries etc.
+ * Several or all data items may be combined into one entity
+ * (DLL, memory-mappable file).</p>
+ *
+ * <p>The data is always preceded by a header that includes
+ * a <code>UDataInfo</code> structure.
+ * The caller's <code>isAcceptable()</code> function is called to make
+ * sure that the data is useful. It may be called several times if it
+ * rejects the data and there is more than one location with data
+ * matching the type and name.</p>
+ *
+ * <p>If <code>path==NULL</code>, then ICU data is loaded.
+ * Otherwise, it is separated into a basename and a basename-less directory string.
+ * The basename is used as the data package name, and the directory is
+ * logically prepended to the ICU data directory string.</p>

+ * Data Management chapter. (http://icu.sourceforge.net/userguide/icudata.html)</p>

+ *             conversion tables with type "cnv".
+ *             This may be <code>NULL</code> or empty.
+ * @param name A string that specifies the name of the data.
+ * @param isAcceptable This function is called to verify that loaded data
+ *                     is useful for the client code. If it returns FALSE
+ *                     for all data items, then <code>udata_openChoice()</code>
+ *                     will return with an error.
+ * @param context Arbitrary parameter to be passed into isAcceptable.
+ * @param pErrorCode An ICU UErrorCode parameter. It must not be <code>NULL</code>.
+ * @return A pointer (handle) to a data memory object, or <code>NULL</code>

+ * The RFC defines 2 operations: ToASCII and ToUnicode. Domain labels 
+ * containing non-ASCII code points are required to be processed by
+ * ToASCII operation before passing it to resolver libraries. Domain names
+ * that are obtained from resolver libraries are required to be processed by
+ * ToUnicode operation before displaying the domain name to the user.
+ * IDNA requires that implementations process input strings with Nameprep
+ * (http://www.ietf.org/rfc/rfc3491.txt), 
+ * which is a profile of Stringprep (http://www.ietf.org/rfc/rfc3454.txt), 
+ * and then with Punycode (http://www.ietf.org/rfc/rfc3492.txt). 
+ * Implementations of IDNA MUST fully implement Nameprep and Punycode; 
+ * neither Nameprep nor Punycode are optional.
+ * The input and output of ToASCII and ToUnicode operations are Unicode 
+ * and are designed to be chainable, i.e., applying ToASCII or ToUnicode operations
+ * multiple times to an input string will yield the same result as applying the operation
+ * once.
+ * ToUnicode(ToUnicode(ToUnicode...(ToUnicode(string)))) == ToUnicode(string)

+ * <h2> ULoc C API for Locale </h2>
+ * A <code>Locale</code> represents a specific geographical, political,
+ * or cultural region. An operation that requires a <code>Locale</code> to perform
+ * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
+ * to tailor information for the user. For example, displaying a number
+ * is a locale-sensitive operation--the number should be formatted
+ * according to the customs/conventions of the user's native country,
+ * region, or culture.  In the C APIs, a locales is simply a const char string.
+ *
+ * <P>
+ * You create a <code>Locale</code> with one of the three options listed below.
+ * Each of the component is separated by '_' in the locale string.

+ * codes as defined by ISO-639.
+ * You can find a full list of these codes at a number of sites, such as:
+ * <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">
+ * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a>
+ *
+ * <P>
+ * The second option includes an additonal <STRONG>ISO Country
+ * Code.</STRONG> These codes are the upper-case two-letter codes
+ * as defined by ISO-3166.
+ * You can find a full list of these codes at a number of sites, such as:
+ * <BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html">
+ * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a>
+ *
+ * <P>
+ * The third option requires another additonal information--the 
+ * <STRONG>Variant.</STRONG>
+ * The Variant codes are vendor and browser-specific.
+ * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
+ * Where there are two variants, separate them with an underscore, and
+ * put the most important one first. For
+ * example, a Traditional Spanish collation might be referenced, with
+ * "ES", "ES", "Traditional_WIN".
+ *
+ * <P>
+ * Because a <code>Locale</code> is just an identifier for a region,
+ * no validity check is performed when you specify a <code>Locale</code>.
+ * If you want to see whether particular resources are available for the
+ * <code>Locale</code> you asked for, you must query those resources. For
+ * example, ask the <code>UNumberFormat</code> for the locales it supports
+ * using its <code>getAvailable</code> method.
+ * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
+ * locale, you get back the best available match, not necessarily
+ * precisely what you asked for. For more information, look at
+ * <code>UResourceBundle</code>.
+ *
+ * <P>
+ * The <code>Locale</code> provides a number of convenient constants
+ * that you can use to specify the commonly used
+ * locales. For example, the following refers to a locale
+ * for the United States:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ *       ULOC_US
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * <P>
+ * Once you've specified a locale you can query it for information about
+ * itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and
+ * <code>uloc_getLanguage</code> to get the ISO Language Code. You can
+ * use <code>uloc_getDisplayCountry</code> to get the
+ * name of the country suitable for displaying to the user. Similarly,
+ * you can use <code>uloc_getDisplayLanguage</code> to get the name of
+ * the language suitable for displaying to the user. Interestingly,
+ * the <code>uloc_getDisplayXXX</code> methods are themselves locale-sensitive
+ * and have two versions: one that uses the default locale and one
+ * that takes a locale as an argument and displays the name or country in
+ * a language appropriate to that locale.
+ *
+ * <P>
+ * The ICU provides a number of services that perform locale-sensitive
+ * operations. For example, the <code>unum_xxx</code> functions format
+ * numbers, currency, or percentages in a locale-sensitive manner. 
+ * </P>
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ *     UErrorCode success = U_ZERO_ERROR;
+ *     UNumberFormat *nf;
+ *     const char* myLocale = "fr_FR";
+ * 
+ *     nf = unum_open( UNUM_DEFAULT, NULL, success );          
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_CURRENCY, NULL, success );
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_PERCENT, NULL, success );   
+ *     unum_close(nf);
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * Each of these methods has two variants; one with an explicit locale
+ * and one without; the latter using the default locale.
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code 
+ * 
+ *     nf = unum_open( UNUM_DEFAULT, myLocale, success );          
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_CURRENCY, myLocale, success );
+ *     unum_close(nf);
+ *     nf = unum_open( UNUM_PERCENT, myLocale, success );   
+ *     unum_close(nf);
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * A <code>Locale</code> is the mechanism for identifying the kind of services
+ * (<code>UNumberFormat</code>) that you would like to get. The locale is
+ * <STRONG>just</STRONG> a mechanism for identifying these services.
+ *
+ * <P>
+ * Each international serivce that performs locale-sensitive operations 
+ * allows you
+ * to get all the available objects of that type. You can sift
+ * through these objects by language, country, or variant,
+ * and use the display names to present a menu to the user.
+ * For example, you can create a menu of all the collation objects
+ * suitable for a given language. Such classes implement these
+ * three class methods:
+ * \htmlonly<blockquote>\endhtmlonly
+ * <pre>
+ * \code
+ *       const char* uloc_getAvailable(int32_t index);
+ *       int32_t uloc_countAvailable();
+ *       int32_t
+ *       uloc_getDisplayName(const char* localeID,
+ *                 const char* inLocaleID, 
+ *                 UChar* result,
+ *                 int32_t maxResultSize,
+ *                  UErrorCode* err);
+ * 
+ * \endcode
+ * </pre>
+ * \htmlonly</blockquote>\endhtmlonly
+ * <P>
+ * Concerning POSIX/RFC1766 Locale IDs, 
+ *  the getLanguage/getCountry/getVariant/getName functions do understand
+ * the POSIX type form of  language_COUNTRY.ENCODING\@VARIANT
+ * and if there is not an ICU-stype variant, uloc_getVariant() for example
+ * will return the one listed after the \@at sign. As well, the hyphen
+ * "-" is recognized as a country/variant separator similarly to RFC1766.
+ * So for example, "en-us" will be interpreted as en_US.  
+ * As a result, uloc_getName() is far from a no-op, and will have the
+ * effect of converting POSIX/RFC1766 IDs into ICU form, although it does
+ * NOT map any of the actual codes (i.e. russian->ru) in any way.
+ * Applications should call uloc_getName() at the point where a locale ID
+ * is coming from an external source (user entry, OS, web browser)
+ * and pass the resulting string to other ICU functions.  For example,
+ * don't use de-de\@EURO as an argument to resourcebundle.

+/**
+ * A mutable set of Unicode characters and multicharacter strings.  Objects of this class
+ * represent <em>character classes</em> used in regular expressions.
+ * A character specifies a subset of Unicode code points.  Legal
+ * code points are U+0000 to U+10FFFF, inclusive.
+ *
+ * <p>The UnicodeSet class is not designed to be subclassed.
+ *
+ * <p><code>UnicodeSet</code> supports two APIs. The first is the
+ * <em>operand</em> API that allows the caller to modify the value of
+ * a <code>UnicodeSet</code> object. It conforms to Java 2's
+ * <code>java.util.Set</code> interface, although
+ * <code>UnicodeSet</code> does not actually implement that
+ * interface. All methods of <code>Set</code> are supported, with the
+ * modification that they take a character range or single character
+ * instead of an <code>Object</code>, and they take a
+ * <code>UnicodeSet</code> instead of a <code>Collection</code>.  The
+ * operand API may be thought of in terms of boolean logic: a boolean
+ * OR is implemented by <code>add</code>, a boolean AND is implemented
+ * by <code>retain</code>, a boolean XOR is implemented by
+ * <code>complement</code> taking an argument, and a boolean NOT is
+ * implemented by <code>complement</code> with no argument.  In terms
+ * of traditional set theory function names, <code>add</code> is a
+ * union, <code>retain</code> is an intersection, <code>remove</code>
+ * is an asymmetric difference, and <code>complement</code> with no
+ * argument is a set complement with respect to the superset range
+ * <code>MIN_VALUE-MAX_VALUE</code>
+ *
+ * <p>The second API is the
+ * <code>applyPattern()</code>/<code>toPattern()</code> API from the
+ * <code>java.text.Format</code>-derived classes.  Unlike the
+ * methods that add characters, add categories, and control the logic
+ * of the set, the method <code>applyPattern()</code> sets all
+ * attributes of a <code>UnicodeSet</code> at once, based on a
+ * string pattern.
+ *
+ * <p><b>Pattern syntax</b></p>
+ *
+ * Patterns are accepted by the constructors and the
+ * <code>applyPattern()</code> methods and returned by the
+ * <code>toPattern()</code> method.  These patterns follow a syntax
+ * similar to that employed by version 8 regular expression character
+ * classes.  Here are some simple examples:

+ *       <td valign="top">All characters in the general category Uppercase Letter</td>
+ *     </tr>
+ *   </table>
+ * \htmlonly</blockquote>\endhtmlonly
+ *
+ * Any character may be preceded by a backslash in order to remove any special
+ * meaning.  White space characters, as defined by UCharacter.isWhitespace(), are
+ * ignored, unless they are escaped.
+ *
+ * <p>Property patterns specify a set of characters having a certain
+ * property as defined by the Unicode standard.  Both the POSIX-like
+ * "[:Lu:]" and the Perl-like syntax "\\p{Lu}" are recognized.  For a
+ * complete list of supported property patterns, see the User's Guide
+ * for UnicodeSet at
+ * <a href="http://icu.sourceforge.net/userguide/unicodeSet.html">
+ * http://icu.sourceforge.net/userguide/unicodeSet.html</a>.
+ * Actual determination of property data is defined by the underlying
+ * Unicode database as implemented by UCharacter.
+ *
+ * <p>Patterns specify individual characters, ranges of characters, and
+ * Unicode property sets.  When elements are concatenated, they
+ * specify their union.  To complement a set, place a '^' immediately
+ * after the opening '['.  Property patterns are inverted by modifying
+ * their delimiters; "[:^foo]" and "\\P{foo}".  In any other location,
+ * '^' has no special meaning.
+ *
+ * <p>Ranges are indicated by placing two a '-' between two
+ * characters, as in "a-z".  This specifies the range of all
+ * characters from the left to the right, in Unicode order.  If the
+ * left character is greater than or equal to the
+ * right character it is a syntax error.  If a '-' occurs as the first
+ * character after the opening '[' or '[^', or if it occurs as the
+ * last character before the closing ']', then it is taken as a
+ * literal.  Thus "[a\-b]", "[-ab]", and "[ab-]" all indicate the same
+ * set of three characters, 'a', 'b', and '-'.
+ *
+ * <p>Sets may be intersected using the '&' operator or the asymmetric
+ * set difference may be taken using the '-' operator, for example,
+ * "[[:L:]&[\\u0000-\\u0FFF]]" indicates the set of all Unicode letters
+ * with values less than 4096.  Operators ('&' and '|') have equal
+ * precedence and bind left-to-right.  Thus
+ * "[[:L:]-[a-z]-[\\u0100-\\u01FF]]" is equivalent to
+ * "[[[:L:]-[a-z]]-[\\u0100-\\u01FF]]".  This only really matters for
+ * difference; intersection is commutative.

+/**
+ * UnicodeString is a string class that stores Unicode characters directly and provides
+ * similar functionality as the Java String and StringBuffer classes.
+ * It is a concrete implementation of the abstract class Replaceable (for transliteration).
+ *
+ * The UnicodeString class is not suitable for subclassing.
+ *
+ * <p>For an overview of Unicode strings in C and C++ see the
+ * <a href="http://icu.sourceforge.net/userguide/strings.html">User Guide Strings chapter</a>.</p>
+ *
+ * <p>In ICU, a Unicode string consists of 16-bit Unicode <em>code units</em>.
+ * A Unicode character may be stored with either one code unit
+ * (the most common case) or with a matched pair of special code units
+ * ("surrogates"). The data type for code units is UChar. 
+ * For single-character handling, a Unicode character code <em>point</em> is a value
+ * in the range 0..0x10ffff. ICU uses the UChar32 type for code points.</p>
+ *
+ * <p>Indexes and offsets into and lengths of strings always count code units, not code points.
+ * This is the same as with multi-byte char* strings in traditional string handling.
+ * Operations on partial strings typically do not test for code point boundaries.
+ * If necessary, the user needs to take care of such boundaries by testing for the code unit
+ * values or by using functions like
+ * UnicodeString::getChar32Start() and UnicodeString::getChar32Limit()
+ * (or, in C, the equivalent macros U16_SET_CP_START() and U16_SET_CP_LIMIT(), see utf.h).</p>
+ *
+ * UnicodeString methods are more lenient with regard to input parameter values
+ * than other ICU APIs. In particular:
+ * - If indexes are out of bounds for a UnicodeString object
+ *   (<0 or >length()) then they are "pinned" to the nearest boundary.
+ * - If primitive string pointer values (e.g., const UChar * or char *)
+ *   for input strings are NULL, then those input string parameters are treated
+ *   as if they pointed to an empty string.
+ *   However, this is <em>not</em> the case for char * parameters for charset names
+ *   or other IDs.
+ * - Most UnicodeString methods do not take a UErrorCode parameter because
+ *   there are usually very few opportunities for failure other than a shortage
+ *   of memory, error codes in low-level C++ string methods would be inconvenient,
+ *   and the error code as the last parameter (ICU convention) would prevent
+ *   the use of default parameter values.
+ *   Instead, such methods set the UnicodeString into a "bogus" state
+ *   (see isBogus()) if an error occurs.
+ *
+ * In string comparisons, two UnicodeString objects that are both "bogus"
+ * compare equal (to be transitive and prevent endless loops in sorting),
+ * and a "bogus" string compares less than any non-"bogus" one.
+ *
+ * Const UnicodeString methods are thread-safe. Multiple threads can use
+ * const methods on the same UnicodeString object simultaneously,
+ * but non-const methods must not be called concurrently (in multiple threads)
+ * with any other (const or non-const) methods.
+ *
+ * Similarly, const UnicodeString & parameters are thread-safe.
+ * One object may be passed in as such a parameter concurrently in multiple threads.
+ * This includes the const UnicodeString & parameters for
+ * copy construction, assignment, and cloning.
+ *
+ * <p>UnicodeString uses several storage methods.
+ * String contents can be stored inside the UnicodeString object itself,
+ * in an allocated and shared buffer, or in an outside buffer that is "aliased".
+ * Most of this is done transparently, but careful aliasing in particular provides
+ * significant performance improvements.
+ * Also, the internal buffer is accessible via special functions.
+ * For details see the
+ * <a href="http://icu.sourceforge.net/userguide/strings.html">User Guide Strings chapter</a>.</p>

+/**
+ * \file
+ * \brief C API: Unicode Normalization 
+ *
+ * <h2>Unicode normalization API</h2>
+ *
+ * <code>unorm_normalize</code> transforms Unicode text into an equivalent composed or
+ * decomposed form, allowing for easier sorting and searching of text.
+ * <code>unorm_normalize</code> supports the standard normalization forms described in
+ * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
+ * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
+ *
+ * Characters with accents or other adornments can be encoded in
+ * several different ways in Unicode.  For example, take the character A-acute.
+ * In Unicode, this can be encoded as a single character (the
+ * "composed" form):
+ *
+ * \code
+ *      00C1    LATIN CAPITAL LETTER A WITH ACUTE
+ * \endcode
+ *
+ * or as two separate characters (the "decomposed" form):
+ *
+ * \code
+ *      0041    LATIN CAPITAL LETTER A
+ *      0301    COMBINING ACUTE ACCENT
+ * \endcode
+ *
+ * To a user of your program, however, both of these sequences should be
+ * treated as the same "user-level" character "A with acute accent".  When you are searching or
+ * comparing text, you must ensure that these two sequences are treated 
+ * equivalently.  In addition, you must handle characters with more than one
+ * accent.  Sometimes the order of a character's combining accents is
+ * significant, while in other cases accent sequences in different orders are
+ * really equivalent.
+ *
+ * Similarly, the string "ffi" can be encoded as three separate letters:
+ *
+ * \code
+ *      0066    LATIN SMALL LETTER F
+ *      0066    LATIN SMALL LETTER F
+ *      0069    LATIN SMALL LETTER I
+ * \endcode
+ *
+ * or as the single character
+ *
+ * \code
+ *      FB03    LATIN SMALL LIGATURE FFI
+ * \endcode
+ *
+ * The ffi ligature is not a distinct semantic character, and strictly speaking
+ * it shouldn't be in Unicode at all, but it was included for compatibility
+ * with existing character sets that already provided it.  The Unicode standard
+ * identifies such characters by giving them "compatibility" decompositions
+ * into the corresponding semantic characters.  When sorting and searching, you
+ * will often want to use these mappings.
+ *
+ * <code>unorm_normalize</code> helps solve these problems by transforming text into the
+ * canonical composed and decomposed forms as shown in the first example above.  
+ * In addition, you can have it perform compatibility decompositions so that 
+ * you can treat compatibility characters the same as their equivalents.
+ * Finally, <code>unorm_normalize</code> rearranges accents into the proper canonical
+ * order, so that you do not have to worry about accent rearrangement on your
+ * own.
+ *
+ * Form FCD, "Fast C or D", is also designed for collation.
+ * It allows to work on strings that are not necessarily normalized
+ * with an algorithm (like in collation) that works under "canonical closure", i.e., it treats precomposed
+ * characters and their decomposed equivalents the same.
+ *
+ * It is not a normalization form because it does not provide for uniqueness of representation. Multiple strings
+ * may be canonically equivalent (their NFDs are identical) and may all conform to FCD without being identical
+ * themselves.
+ *
+ * The form is defined such that the "raw decomposition", the recursive canonical decomposition of each character,
+ * results in a string that is canonically ordered. This means that precomposed characters are allowed for as long
+ * as their decompositions do not need canonical reordering.
+ *
+ * Its advantage for a process like collation is that all NFD and most NFC texts - and many unnormalized texts -
+ * already conform to FCD and do not need to be normalized (NFD) for such a process. The FCD quick check will
+ * return UNORM_YES for most strings in practice.
+ *
+ * unorm_normalize(UNORM_FCD) may be implemented with UNORM_NFD.
+ *
+ * For more details on FCD see the collation design document:
+ * http://dev.icu-project.org/cgi-bin/viewcvs.cgi/~checkout~/icuhtml/design/collation/ICU_collation_design.htm
+ *
+ * ICU collation performs either NFD or FCD normalization automatically if normalization
+ * is turned on for the collator object.
+ * Beyond collation and string search, normalized strings may be useful for string equivalence comparisons,
+ * transliteration/transcription, unique representations, etc.
+ *
+ * The W3C generally recommends to exchange texts in NFC.
+ * Note also that most legacy character encodings use only precomposed forms and often do not
+ * encode any combining marks by themselves. For conversion to such character encodings the
+ * Unicode text needs to be normalized to NFC.
+ * For more usage examples, see the Unicode Standard Annex.

+/**
+ * Iterative normalization forward.
+ * This function (together with unorm_previous) is somewhat
+ * similar to the C++ Normalizer class (see its non-static functions).
+ *
+ * Iterative normalization is useful when only a small portion of a longer
+ * string/text needs to be processed.
+ *
+ * For example, the likelihood may be high that processing the first 10% of some
+ * text will be sufficient to find certain data.
+ * Another example: When one wants to concatenate two normalized strings and get a
+ * normalized result, it is much more efficient to normalize just a small part of
+ * the result around the concatenation place instead of re-normalizing everything.
+ *
+ * The input text is an instance of the C character iteration API UCharIterator.
+ * It may wrap around a simple string, a CharacterIterator, a Replaceable, or any
+ * other kind of text object.
+ *
+ * If a buffer overflow occurs, then the caller needs to reset the iterator to the
+ * old index and call the function again with a larger buffer - if the caller cares
+ * for the actual output.
+ * Regardless of the output buffer, the iterator will always be moved to the next
+ * normalization boundary.
+ *
+ * This function (like unorm_previous) serves two purposes:
+ *
+ * 1) To find the next boundary so that the normalization of the part of the text
+ * from the current position to that boundary does not affect and is not affected
+ * by the part of the text beyond that boundary.
+ *
+ * 2) To normalize the text up to the boundary.
+ *
+ * The second step is optional, per the doNormalize parameter.
+ * It is omitted for operations like string concatenation, where the two adjacent
+ * string ends need to be normalized together.
+ * In such a case, the output buffer will just contain a copy of the text up to the
+ * boundary.
+ *
+ * pNeededToNormalize is an output-only parameter. Its output value is only defined
+ * if normalization was requested (doNormalize) and successful (especially, no
+ * buffer overflow).
+ * It is useful for operations like a normalizing transliterator, where one would
+ * not want to replace a piece of text if it is not modified.
+ *
+ * If doNormalize==TRUE and pNeededToNormalize!=NULL then *pNeeded... is set TRUE
+ * if the normalization was necessary.
+ *
+ * If doNormalize==FALSE then *pNeededToNormalize will be set to FALSE.
+ *
+ * If the buffer overflows, then *pNeededToNormalize will be undefined;
+ * essentially, whenever U_FAILURE is true (like in buffer overflows), this result
+ * will be undefined.
+ *
+ * @param src The input text in the form of a C character iterator.
+ * @param dest The output buffer; can be NULL if destCapacity==0 for pure preflighting.
+ * @param destCapacity The number of UChars that fit into dest.
+ * @param mode The normalization mode.
+ * @param options The normalization options, ORed together (0 for no options).
+ * @param doNormalize Indicates if the source text up to the next boundary
+ *                    is to be normalized (TRUE) or just copied (FALSE).
+ * @param pNeededToNormalize Output flag indicating if the normalization resulted in
+ *                           different text from the input.
+ *                           Not defined if an error occurs including buffer overflow.
+ *                           Always FALSE if !doNormalize.

+ * <h2>C API: Resource Bundle</h2>
+ *
+ * C API representing a collection of resource information pertaining to a given

+ * locale and then ask it for individual resources.
+ * <P>
+ * Resource bundles in ICU4C are currently defined using text files which conform to the following
+ * <a href="http://dev.icu-project.org/cgi-bin/viewcvs.cgi/~checkout~/icuhtml/design/bnf_rb.txt">BNF definition</a>.
+ * More on resource bundle concepts and syntax can be found in the

+ *
+ * Starting with ICU 3.6, constants for most ISO 15924 script codes

+ * For scripts for which there are codes in ISO 15924 but which are not

+ * associated with those scripts.
+ *
+ * For example, there are no characters that have a UCD script code of
+ * Hans or Hant. All Han ideographs have the Hani script code.
+ * The Hans and Hant script codes are used with CLDR data.

+ * 
+ */
+
+/**
+ * Shape Arabic text on a character basis.
+ *
+ * <p>This function performs basic operations for "shaping" Arabic text. It is most
+ * useful for use with legacy data formats and legacy display technology
+ * (simple terminals). All operations are performed on Unicode characters.</p>
+ *
+ * <p>Text-based shaping means that some character code points in the text are
+ * replaced by others depending on the context. It transforms one kind of text
+ * into another. In comparison, modern displays for Arabic text select
+ * appropriate, context-dependent font glyphs for each text element, which means
+ * that they transform text into a glyph vector.</p>
+ *
+ * <p>Text transformations are necessary when modern display technology is not
+ * available or when text needs to be transformed to or from legacy formats that
+ * use "shaped" characters. Since the Arabic script is cursive, connecting
+ * adjacent letters to each other, computers select images for each letter based
+ * on the surrounding letters. This usually results in four images per Arabic
+ * letter: initial, middle, final, and isolated forms. In Unicode, on the other
+ * hand, letters are normally stored abstract, and a display system is expected
+ * to select the necessary glyphs. (This makes searching and other text
+ * processing easier because the same letter has only one code.) It is possible
+ * to mimic this with text transformations because there are characters in
+ * Unicode that are rendered as letters with a specific shape
+ * (or cursive connectivity). They were included for interoperability with
+ * legacy systems and codepages, and for unsophisticated display systems.</p>
+ *
+ * <p>A second kind of text transformations is supported for Arabic digits:
+ * For compatibility with legacy codepages that only include European digits,
+ * it is possible to replace one set of digits by another, changing the
+ * character code points. These operations can be performed for either
+ * Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic
+ * digits (U+06f0...U+06f9).</p>
+ *
+ * <p>Some replacements may result in more or fewer characters (code points).
+ * By default, this means that the destination buffer may receive text with a
+ * length different from the source length. Some legacy systems rely on the
+ * length of the text to be constant. They expect extra spaces to be added
+ * or consumed either next to the affected character or at the end of the
+ * text.</p>
+ *
+ * <p>For details about the available operations, see the description of the
+ * <code>U_SHAPE_...</code> options.</p>
+ *
+ * @param source The input text.
+ *
+ * @param sourceLength The number of UChars in <code>source</code>.
+ *
+ * @param dest The destination buffer that will receive the results of the
+ *             requested operations. It may be <code>NULL</code> only if
+ *             <code>destSize</code> is 0. The source and destination must not
+ *             overlap.
+ *
+ * @param destSize The size (capacity) of the destination buffer in UChars.
+ *                 If <code>destSize</code> is 0, then no output is produced,
+ *                 but the necessary buffer size is returned ("preflighting").
+ *
+ * @param options This is a 32-bit set of flags that specify the operations
+ *                that are performed on the input text. If no error occurs,
+ *                then the result will always be written to the destination
+ *                buffer.
+ *
+ * @param pErrorCode must be a valid pointer to an error code value,
+ *        which must not indicate a failure before the function call.
+ *
+ * @return The number of UChars written to the destination buffer.
+ *         If an error occured, then no output was written, or it may be
+ *         incomplete. If <code>U_BUFFER_OVERFLOW_ERROR</code> is set, then
+ *         the return value indicates the necessary destination buffer size.

+ * \file
+ * \brief C API: Unicode string handling functions
+ *
+ * These C API functions provide general Unicode string handling.
+ *
+ * Some functions are equivalent in name, signature, and behavior to the ANSI C <string.h>
+ * functions. (For example, they do not check for bad arguments like NULL string pointers.)
+ * In some cases, only the thread-safe variant of such a function is implemented here
+ * (see u_strtok_r()).
+ *
+ * Other functions provide more Unicode-specific functionality like locale-specific
+ * upper/lower-casing and string comparison in code point order.
+ *
+ * ICU uses 16-bit Unicode (UTF-16) in the form of arrays of UChar code units.
+ * UTF-16 encodes each Unicode code point with either one or two UChar code units.
+ * (This is the default form of Unicode, and a forward-compatible extension of the original,
+ * fixed-width form that was known as UCS-2. UTF-16 superseded UCS-2 with Unicode 2.0
+ * in 1996.)
+ *
+ * Some APIs accept a 32-bit UChar32 value for a single code point.
+ *
+ * ICU also handles 16-bit Unicode text with unpaired surrogates.
+ * Such text is not well-formed UTF-16.
+ * Code-point-related functions treat unpaired surrogates as surrogate code points,
+ * i.e., as separate units.
+ *
+ * Although UTF-16 is a variable-width encoding form (like some legacy multi-byte encodings),
+ * it is much more efficient even for random access because the code unit values
+ * for single-unit characters vs. lead units vs. trail units are completely disjoint.
+ * This means that it is easy to determine character (code point) boundaries from
+ * random offsets in the string.
+ *
+ * Unicode (UTF-16) string processing is optimized for the single-unit case.
+ * Although it is important to support supplementary characters
+ * (which use pairs of lead/trail code units called "surrogates"),
+ * their occurrence is rare. Almost all characters in modern use require only
+ * a single UChar code unit (i.e., their code point values are <=0xffff).
+ *
+ * For more details see the User Guide Strings chapter (http://icu.sourceforge.net/userguide/strings.html).
+ * For a discussion of the handling of unpaired surrogates see also
+ * Jitterbug 2145 and its icu mailing list proposal on 2002-sep-18.

+/**
+ * \file
+ * \brief C API: Abstract Unicode Text API
+ *
+ * The Text Access API provides a means to allow text that is stored in alternative
+ * formats to work with ICU services.  ICU normally operates on text that is
+ * stored in UTF-16 format, in (UChar *) arrays for the C APIs or as type
+ * UnicodeString for C++ APIs.
+ *
+ * ICU Text Access allows other formats, such as UTF-8 or non-contiguous
+ * UTF-16 strings, to be placed in a UText wrapper and then passed to ICU services.
+ *
+ * There are three general classes of usage for UText:
+ *
+ *     Application Level Use.  This is the simplest usage - applications would
+ *     use one of the utext_open() functions on their input text, and pass
+ *     the resulting UText to the desired ICU service.
+ *
+ *     Second is usage in ICU Services, such as break iteration, that will need to
+ *     operate on input presented to them as a UText.  These implementations
+ *     will need to use the iteration and related UText functions to gain
+ *     access to the actual text.
+ *
+ *     The third class of UText users are "text providers."  These are the
+ *     UText implementations for the various text storage formats.  An application
+ *     or system with a unique text storage format can implement a set of
+ *     UText provider functions for that format, which will then allow
+ *     ICU services to operate on that format.
+ *
+ *
+ * <em>Iterating over text</em>
+ *
+ * Here is sample code for a forward iteration over the contents of a UText
+ *
+ * \code
+ *    UChar32  c;
+ *    UText    *ut = whatever();
+ *
+ *    for (c=utext_next32From(ut, 0); c>=0; c=utext_next32(ut)) {
+ *       // do whatever with the codepoint c here.
+ *    }
+ * \endcode
+ *
+ * And here is similar code to iterate in the reverse direction, from the end
+ * of the text towards the beginning.
+ *
+ * \code
+ *    UChar32  c;
+ *    UText    *ut = whatever();
+ *    int      textLength = utext_nativeLength(ut);
+ *    for (c=utext_previous32From(ut, textLength); c>=0; c=utext_previous32(ut)) {
+ *       // do whatever with the codepoint c here.
+ *    }
+ * \endcode
+ *
+ * <em>Characters and Indexing</em>
+ *
+ * Indexing into text by UText functions is nearly always in terms of the native
+ * indexing of the underlying text storage.  The storage format could be UTF-8
+ * or UTF-32, for example.  When coding to the UText access API, no assumptions
+ * can be made regarding the size of characters, or how far an index
+ * may move when iterating between characters.
+ *
+ * All indices supplied to UText functions are pinned to the length of the
+ * text.  An out-of-bounds index is not considered to be an error, but is
+ * adjusted to be in the range  0 <= index <= length of input text.
+ *
+ *
+ * When an index position is returned from a UText function, it will be
+ * a native index to the underlying text.  In the case of multi-unit characters,
+ * it will  always refer to the first position of the character,
+ * never to the interior.  This is essentially the same thing as saying that
+ * a returned index will always point to a boundary between characters.
+ *
+ * When a native index is supplied to a UText function, all indices that
+ * refer to any part of a multi-unit character representation are considered
+ * to be equivalent.  In the case of multi-unit characters, an incoming index
+ * will be logically normalized to refer to the start of the character.
+ * 
+ * It is possible to test whether a native index is on a code point boundary
+ * by doing a utext_setNativeIndex() followed by a utext_getNativeIndex().
+ * If the index is returned unchanged, it was on a code point boundary.  If
+ * an adjusted index is returned, the original index referred to the
+ * interior of a character.
+ *
+ * <em>Conventions for calling UText functions</em>
+ *
+ * Most UText access functions have as their first parameter a (UText *) pointer,
+ * which specifies the UText to be used.  Unless otherwise noted, the
+ * pointer must refer to a valid, open UText.  Attempting to
+ * use a closed UText or passing a NULL pointer is a programming error and
+ * will produce undefined results or NULL pointer exceptions.
+ * 
+ * The UText_Open family of functions can either open an existing (closed)
+ * UText, or heap allocate a new UText.  Here is sample code for creating
+ * a stack-allocated UText.
+ *
+ * \code
+ *    char     *s = whatever();  // A utf-8 string 
+ *    U_ErrorCode status = U_ZERO_ERROR;
+ *    UText    ut = UTEXT_INITIALIZER;
+ *    utext_openUTF8(ut, s, -1, &status);
+ *    if (U_FAILURE(status)) {
+ *        // error handling
+ *    } else {
+ *        // work with the UText
+ *    }
+ * \endcode
+ *
+ * Any existing UText passed to an open function _must_ have been initialized, 
+ * either by the UTEXT_INITIALIZER, or by having been originally heap-allocated
+ * by an open function.  Passing NULL will cause the open function to
+ * heap-allocate and fully initialize a new UText.

+/**
+ * \file
+ * \brief C API: Code point macros
+ *
+ * This file defines macros for checking whether a code point is
+ * a surrogate or a non-character etc.
+ *
+ * The UChar and UChar32 data types for Unicode code units and code points
+ * are defined in umachines.h because they can be machine-dependent.
+ *
+ * utf.h is included by utypes.h and itself includes utf8.h and utf16.h after some
+ * common definitions. Those files define macros for efficiently getting code points
+ * in and out of UTF-8/16 strings.
+ * utf16.h macros have "U16_" prefixes.
+ * utf8.h defines similar macros with "U8_" prefixes for UTF-8 string handling.
+ *
+ * ICU processes 16-bit Unicode strings.
+ * Most of the time, such strings are well-formed UTF-16.
+ * Single, unpaired surrogates must be handled as well, and are treated in ICU
+ * like regular code points where possible.
+ * (Pairs of surrogate code points are indistinguishable from supplementary
+ * code points encoded as pairs of supplementary code units.)
+ *
+ * In fact, almost all Unicode code points in normal text (>99%)
+ * are on the BMP (<=U+ffff) and even <=U+d7ff.
+ * ICU functions handle supplementary code points (U+10000..U+10ffff)
+ * but are optimized for the much more frequently occurring BMP code points.
+ *
+ * utf.h defines UChar to be an unsigned 16-bit integer. If this matches wchar_t, then
+ * UChar is defined to be exactly wchar_t, otherwise uint16_t.
+ *
+ * UChar32 is defined to be a signed 32-bit integer (int32_t), large enough for a 21-bit
+ * Unicode code point (Unicode scalar value, 0..0x10ffff).
+ * Before ICU 2.4, the definition of UChar32 was similarly platform-dependent as
+ * the definition of UChar. For details see the documentation for UChar32 itself.
+ *
+ * utf.h also defines a small number of C macros for single Unicode code points.
+ * These are simple checks for surrogates and non-characters.
+ * For actual Unicode character properties see uchar.h.
+ *
+ * By default, string operations must be done with error checking in case
+ * a string is not well-formed UTF-16.
+ * The macros will detect if a surrogate code unit is unpaired
+ * (lead unit without trail unit or vice versa) and just return the unit itself
+ * as the code point.
+ * (It is an accidental property of Unicode and UTF-16 that all
+ * malformed sequences can be expressed unambiguously with a distinct subrange
+ * of Unicode code points.)
+ *
+ * The regular "safe" macros require that the initial, passed-in string index
+ * is within bounds. They only check the index when they read more than one
+ * code unit. This is usually done with code similar to the following loop:
+ * <pre>while(i<length) {
+ *   U16_NEXT(s, i, length, c);
+ *   // use c
+ * }</pre>
+ *
+ * When it is safe to assume that text is well-formed UTF-16
+ * (does not contain single, unpaired surrogates), then one can use
+ * U16_..._UNSAFE macros.
+ * These do not check for proper code unit sequences or truncated text and may
+ * yield wrong results or even cause a crash if they are used with "malformed"
+ * text.
+ * In practice, U16_..._UNSAFE macros will produce slightly less code but
+ * should not be faster because the processing is only different when a
+ * surrogate code unit is detected, which will be rare.
+ *
+ * Similarly for UTF-8, there are "safe" macros without a suffix,
+ * and U8_..._UNSAFE versions.
+ * The performance differences are much larger here because UTF-8 provides so
+ * many opportunities for malformed sequences.
+ * The unsafe UTF-8 macros are entirely implemented inside the macro definitions
+ * and are fast, while the safe UTF-8 macros call functions for all but the
+ * trivial (ASCII) cases.
+ * (ICU 3.6 optimizes U8_NEXT() and U8_APPEND() to handle most other common
+ * characters inline as well.)
+ *
+ * Unlike with UTF-16, malformed sequences cannot be expressed with distinct
+ * code point values (0..U+10ffff). They are indicated with negative values instead.
+ *
+ * For more information see the ICU User Guide Strings chapter
+ * (http://icu.sourceforge.net/userguide/strings.html).
+ *
+ * <em>Usage:</em>
+ * ICU coding guidelines for if() statements should be followed when using these macros.
+ * Compound statements (curly braces {}) must be used  for if-else-while... 
+ * bodies and all macro statements should be terminated with semicolon.

+ * \brief C API: Deprecated macros for Unicode string handling
+ */
+
+/**
+ * 
+ * The macros in utf_old.h are all deprecated and their use discouraged.
+ * Some of the design principles behind the set of UTF macros
+ * have changed or proved impractical.
+ * Almost all of the old "UTF macros" are at least renamed.
+ * If you are looking for a new equivalent to an old macro, please see the
+ * comment at the old one.
+ *
+ * utf_old.h is included by utf.h after unicode/umachine.h
+ * and some common definitions, to not break old code.
+ *
+ * Brief summary of reasons for deprecation:
+ * - Switch on UTF_SIZE (selection of UTF-8/16/32 default string processing)
+ *   was impractical.
+ * - Switch on UTF_SAFE etc. (selection of unsafe/safe/strict default string processing)
+ *   was of little use and impractical.
+ * - Whole classes of macros became obsolete outside of the UTF_SIZE/UTF_SAFE
+ *   selection framework: UTF32_ macros (all trivial)
+ *   and UTF_ default and intermediate macros (all aliases).
+ * - The selection framework also caused many macro aliases.
+ * - Change in Unicode standard: "irregular" sequences (3.0) became illegal (3.2).
+ * - Change of language in Unicode standard:
+ *   Growing distinction between internal x-bit Unicode strings and external UTF-x
+ *   forms, with the former more lenient.
+ *   Suggests renaming of UTF16_ macros to U16_.
+ * - The prefix "UTF_" without a width number confused some users.
+ * - "Safe" append macros needed the addition of an error indicator output.
+ * - "Safe" UTF-8 macros used legitimate (if rarely used) code point values
+ *   to indicate error conditions.
+ * - The use of the "_CHAR" infix for code point operations confused some users.
+ *
+ * More details:
+ *
+ * Until ICU 2.2, utf.h theoretically allowed to choose among UTF-8/16/32
+ * for string processing, and among unsafe/safe/strict default macros for that.
+ *
+ * It proved nearly impossible to write non-trivial, high-performance code
+ * that is UTF-generic.
+ * Unsafe default macros would be dangerous for default string processing,
+ * and the main reason for the "strict" versions disappeared:
+ * Between Unicode 3.0 and 3.2 all "irregular" UTF-8 sequences became illegal.
+ * The only other conditions that "strict" checked for were non-characters,
+ * which are valid during processing. Only during text input/output should they
+ * be checked, and at that time other well-formedness checks may be
+ * necessary or useful as well.
+ * This can still be done by using U16_NEXT and U_IS_UNICODE_NONCHAR
+ * or U_IS_UNICODE_CHAR.
+ *
+ * The old UTF8_..._SAFE macros also used some normal Unicode code points
+ * to indicate malformed sequences.
+ * The new UTF8_ macros without suffix use negative values instead.
+ *
+ * The entire contents of utf32.h was moved here without replacement
+ * because all those macros were trivial and
+ * were meaningful only in the framework of choosing the UTF size.
+ *
+ * See Jitterbug 2150 and its discussion on the ICU mailing list
+ * in September 2002.
+ *
+ * <hr>
+ *
+ * <em>Obsolete part</em> of pre-ICU 2.4 utf.h file documentation:
+ *
+ * <p>The original concept for these files was for ICU to allow
+ * in principle to set which UTF (UTF-8/16/32) is used internally
+ * by defining UTF_SIZE to either 8, 16, or 32. utf.h would then define the UChar type
+ * accordingly. UTF-16 was the default.</p>
+ *
+ * <p>This concept has been abandoned.
+ * A lot of the ICU source code assumes UChar strings are in UTF-16.
+ * This is especially true for low-level code like
+ * conversion, normalization, and collation.
+ * The utf.h header enforces the default of UTF-16.
+ * The UTF-8 and UTF-32 macros remain for now for completeness and backward compatibility.</p>
+ *
+ * <p>Accordingly, utf.h defines UChar to be an unsigned 16-bit integer. If this matches wchar_t, then
+ * UChar is defined to be exactly wchar_t, otherwise uint16_t.</p>
+ *
+ * <p>UChar32 is defined to be a signed 32-bit integer (int32_t), large enough for a 21-bit
+ * Unicode code point (Unicode scalar value, 0..0x10ffff).
+ * Before ICU 2.4, the definition of UChar32 was similarly platform-dependent as
+ * the definition of UChar. For details see the documentation for UChar32 itself.</p>
+ *
+ * <p>utf.h also defines a number of C macros for handling single Unicode code points and
+ * for using UTF Unicode strings. It includes utf8.h, utf16.h, and utf32.h for the actual
+ * implementations of those macros and then aliases one set of them (for UTF-16) for general use.
+ * The UTF-specific macros have the UTF size in the macro name prefixes (UTF16_...), while
+ * the general alias macros always begin with UTF_...</p>
+ *
+ * <p>Many string operations can be done with or without error checking.
+ * Where such a distinction is useful, there are two versions of the macros, "unsafe" and "safe"
+ * ones with ..._UNSAFE and ..._SAFE suffixes. The unsafe macros are fast but may cause
+ * program failures if the strings are not well-formed. The safe macros have an additional, boolean
+ * parameter "strict". If strict is FALSE, then only illegal sequences are detected.
+ * Otherwise, irregular sequences and non-characters are detected as well (like single surrogates).
+ * Safe macros return special error code points for illegal/irregular sequences:
+ * Typically, U+ffff, or values that would result in a code unit sequence of the same length
+ * as the erroneous input sequence.<br>
+ * Note that _UNSAFE macros have fewer parameters: They do not have the strictness parameter, and
+ * they do not have start/length parameters for boundary checking.</p>
+ *
+ * <p>Here, the macros are aliased in two steps:
+ * In the first step, the UTF-specific macros with UTF16_ prefix and _UNSAFE and _SAFE suffixes are
+ * aliased according to the UTF_SIZE to macros with UTF_ prefix and the same suffixes and signatures.
+ * Then, in a second step, the default, general alias macros are set to use either the unsafe or
+ * the safe/not strict (default) or the safe/strict macro;
+ * these general macros do not have a strictness parameter.</p>
+ *
+ * <p>It is possible to change the default choice for the general alias macros to be unsafe, safe/not strict or safe/strict.
+ * The default is safe/not strict. It is not recommended to select the unsafe macros as the basis for
+ * Unicode string handling in ICU! To select this, define UTF_SAFE, UTF_STRICT, or UTF_UNSAFE.</p>

+ *
+ * ICU trace format string syntax
+ *
+ * Format Strings are passed to UTraceData functions, and define the
+ * number and types of the trace data being passed on each call.
+ *
+ * The UTraceData function, which is supplied by the application,
+ * not by ICU, can either forward the trace data (passed via
+ * varargs) and the format string back to ICU for formatting into
+ * a displayable string, or it can interpret the format itself,
+ * and do as it wishes with the trace data.
+ *
+ *
+ * Goals for the format string
+ * - basic data output
+ * - easy to use for trace programmer
+ * - sufficient provision for data types for trace output readability
+ * - well-defined types and binary portable APIs
+ *
+ * Non-goals
+ * - printf compatibility
+ * - fancy formatting
+ * - argument reordering and other internationalization features
+ *
+ * ICU trace format strings contain plain text with argument inserts,
+ * much like standard printf format strings.
+ * Each insert begins with a '%', then optionally contains a 'v',
+ * then exactly one type character.
+ * Two '%' in a row represent a '%' instead of an insert.
+ * The trace format strings need not have \n at the end.
+ *
+ *
+ * Types
+ * -----
+ *
+ * Type characters:
+ * - c A char character in the default codepage.
+ * - s A NUL-terminated char * string in the default codepage.
+ * - S A UChar * string.  Requires two params, (ptr, length).  Length=-1 for nul term.
+ * - b A byte (8-bit integer).
+ * - h A 16-bit integer.  Also a 16 bit Unicode code unit.
+ * - d A 32-bit integer.  Also a 20 bit Unicode code point value. 
+ * - l A 64-bit integer.
+ * - p A data pointer.
+ *
+ * Vectors
+ * -------
+ *
+ * If the 'v' is not specified, then one item of the specified type
+ * is passed in.
+ * If the 'v' (for "vector") is specified, then a vector of items of the
+ * specified type is passed in, via a pointer to the first item
+ * and an int32_t value for the length of the vector.
+ * Length==-1 means zero or NUL termination.  Works for vectors of all types.
+ *
+ * Note:  %vS is a vector of (UChar *) strings.  The strings must
+ *        be nul terminated as there is no way to provide a
+ *        separate length parameter for each string.  The length
+ *        parameter (required for all vectors) is the number of
+ *        strings, not the length of the strings.
+ *
+ * Examples
+ * --------
+ *
+ * These examples show the parameters that will be passed to an application's
+ *   UTraceData() function for various formats.
+ *
+ * - the precise formatting is up to the application!
+ * - the examples use type casts for arguments only to _show_ the types of
+ *   arguments without needing variable declarations in the examples;
+ *   the type casts will not be necessary in actual code
+ *
+ * UTraceDataFunc(context, fnNumber, level,

+ *
+ * <p>Those "invariant characters" should be all the uppercase and lowercase
+ * latin letters, the digits, the space, and "basic punctuation".
+ * Also, '\\n', '\\r', '\\t' should be available.</p>
+ *
+ * <p>The list of "invariant characters" is:<br>
+ * \code
+ *    A-Z  a-z  0-9  SPACE  "  %  &amp;  '  (  )  *  +  ,  -  .  /  :  ;  <  =  >  ?  _

+ *
+ * <p>This matches the IBM Syntactic Character Set (CS 640).</p>
+ *
+ * <p>In other words, all the graphic characters in 7-bit ASCII should
+ * be safely accessible except the following:</p>
