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. | |
