 A bug with NSMutableString#sub!.  Characters are corrupted when replaced
 with non-ASCII characters.  This does not happen with 'gsub!' nor
 'sub/gsub'.  And as pointed out by Vincent, this also happens with
 'self[]'.

 Here's the code written by Vincent.

 {{{
 framework 'Cocoa'

 s1 = NSMutableString.stringWithString("this is a test script.")
 s1.sub!(/test/, "あ")
 puts s1 #=> this is a ￣ﾁﾂ script.

 s2 = NSMutableString.stringWithString("this is a test script.")
 s2[10..14] = "あ"
 puts s2 #=> this is a ￣ﾁﾂ script.
 }}}
