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