Comment:

 In fact both results are incorrect. Running it in 1.9 (adding {{{#coding:
 utf-8}}} at the start line of the file) raises an "invalid byte sequence
 in UTF-8 (ArgumentError)".

 I don't have MacRuby handy, but looking at the source code there are a few
 differences with the behavior of 1.9:
  * {{{String#each_char}}} and {{{String#ord}}} do not throw an exception
 when the encoding is invalid
  * {{{String#ord}}} in ASCII-8BIT returns 0xFFFF for non ASCII-characters
 (it should simply return the byte value)

 Note that to iterate other the bytes of a string, you should use
 {{{String#each_byte}}} instead of {{{String#each_char}}}.
