+wxWidgets has support for multiple font encodings starting from release 2.2.
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 alphabetes and here other encodings come into play. Please

note that we will only discuss 8-bit fonts here and not

\helpref{wxFont}{wxfont} itself, but also

for Western Europe) and CP1251 (WinLatin1, standard code page for English
versions of Windows) and there are more of them for other encodings.

-To allow to see clearer in this, \helpref{wxFontEnumerator}{wxfontenumerator}
+To clarify, the \helpref{wxFontEnumerator}{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

\helpref{wxFontEnumerator}{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 \helpref{wxConfig}{wxconfigoverview} object. Of
course, it would be fairly useless if it tried to determine these mappings by
