   7
   8 This class converts between the UTF-8 encoding and Unicode.
   9 It has one predefined instance, {\bf wxConvUTF8}.

  25
  26 UTF-8 is a compatibility encoding used to encode Unicode text into anything that was
  27 originally written for 8-bit strings, including (but not limited to) filenames, transfer
  28 protocols, and database fields. Notable properties include:
  29
  30 \begin{itemize}
  31 \item Variable-length encoding able to encode up to 31 bits per character
  32 \item ASCII characters (character values under 128) are encoded as plain ASCII
  33 (1 byte per character)
  34 \item Null bytes do not occur in the encoding, except when there's an actual Unicode
  35 null character
  36 \item Preserves sort ordering for plain 8-bit comparison routines like strcmp()
  37 \item High bit patterns unambiguates character boundaries, and makes it easy to
  38 detect whether a string is encoded with UTF-8 or not
  39 \end{itemize}
  40
  41 All of these properties make UTF-8 a very favorable solution in any situation
  42 where full Unicode character support is desired while remaining compatible with
  43 code written with only 8-bit extended-ASCII characters in mind.
