- wxWidgets has support for multiple font encodings.
- By encoding we mean here the mapping between the character codes and the
- letters. Probably the most well-known encoding is (7 bit) ASCII one which is
- used almost universally now to represent the letters of the English alphabet
- and some other common characters. However, it is not enough to represent the
- letters of foreign alphabets and here other encodings come into play. Please
- note that we will only discuss 8-bit fonts here and not
- #Unicode.
- Font encoding support is ensured by several classes:
- #wxFont itself, but also
- #wxFontEnumerator and
- #wxFontMapper. wxFont encoding support is reflected by
- a (new) constructor parameter @e encoding which takes one of the following
- values (elements of enumeration type @c wxFontEncoding):
-
-
-
-
-
-
- wxFONTENCODING_SYSTEM
-
-
-
-
- The default encoding of the underlying
- operating system (notice that this might be a "foreign" encoding for foreign
- versions of Windows 9x/NT).
-
-
-
-
-
- wxFONTENCODING_DEFAULT
-
-
-
-
- The applications default encoding as
- returned by wxFont::GetDefaultEncoding. On
- program startup, the applications default encoding is the same as
- wxFONTENCODING_SYSTEM, but may be changed to make all the fonts created later
- to use it (by default).
-
-
-
-
-
- wxFONTENCODING_ISO8859_1..15
-
-
-
-
- ISO8859 family encodings which are
- usually used by all non-Microsoft operating systems
-
-
-
-
-
- wxFONTENCODING_KOI8
-
-
-
-
- Standard Cyrillic encoding for the Internet
- (but see also wxFONTENCODING_ISO8859_5 and wxFONTENCODING_CP1251)
-
-
-
-
-
- wxFONTENCODING_CP1250
-
-
-
-
- Microsoft analogue of ISO8859-2
-
-
-
-
-
- wxFONTENCODING_CP1251
-
-
-
-
- Microsoft analogue of ISO8859-5
-
-
-
-
-
- wxFONTENCODING_CP1252
-
-
-
-
- Microsoft analogue of ISO8859-1
-
-
-
-
-
- As you may see, Microsoft's encoding partly mirror the standard ISO8859 ones,
- but there are (minor) differences even between ISO8859-1 (Latin1, ISO encoding
- for Western Europe) and CP1251 (WinLatin1, standard code page for English
- versions of Windows) and there are more of them for other encodings.
- The situation is particularly complicated with Cyrillic encodings for which
- (more than) three incompatible encodings exist: KOI8 (the old standard, widely
- used on the Internet), ISO8859-5 (ISO standard for Cyrillic) and CP1251
- (WinCyrillic).
- This abundance of (incompatible) encodings should make it clear that using
- encodings is less easy than it might seem. The problems arise both from the
- fact that the standard encodings for the given language (say Russian, which is
- written in Cyrillic) are different on different platforms and because the
- fonts in the given encoding might just not be installed (this is especially a
- problem with Unix, or, in general, non-Win32 systems).
- To clarify, the #wxFontEnumerator
- class may be used to enumerate both all available encodings and to find the
- facename(s) in which the given encoding exists. If you can find the font in
- the correct encoding with wxFontEnumerator then your troubles are over, but,
- unfortunately, sometimes this is not enough. For example, there is no standard
- way (that I know of, please tell me if you do!) to find a font on a Windows system
- for KOI8 encoding (only for WinCyrillic one which is quite different), so
- #wxFontEnumerator will never return one, even if
- the user has installed a KOI8 font on his system.
- To solve this problem, a #wxFontMapper class is provided.
- This class stores the mapping between the encodings and the font face
- names which support them in #wxConfig object. Of
- course, it would be fairly useless if it tried to determine these mappings by
- itself, so, instead, it (optionally) asks the user and remembers his answers
- so that the next time the program will automatically choose the correct font.
- All these topics are illustrated by the @ref samplefont_overview;
- please refer to it and the documentation of the classes mentioned here for
- further explanations.
