- 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
- (see @ref overview_unicode).

- 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).
+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.
- 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.

- 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 page_utils_samples_font;
- please refer to it and the documentation of the classes mentioned here for
- further explanations.
