Я тут накатал письмо для FoX списка рассылки, придержал его, чтобы
сначала скачать и собрать последний FoX, дабы посмотреть, не изменилось ли что,
 да подумал, может кто в этом списке рассылки сможет сказать что-нибудь 
по поводу моих проблем.

Вот мое письмо

Hello all,

Though I code FoX using FXRuby, the questions I have are related directly to the FoX library.


When creating an FXFont instance, we set the encoding property. Encodings related
to the Russian language declared in FXFont.h are

  FONTENCODING_ISO_8859_5 -  cyrillic ISO charset, used very rarely
  FONTENCODING_CYRILLIC   -  the same


  FONTENCODING_KOI8_R     -  KOI8-R, Russian charset traditionally used in Unix, now in Linux
  FONTENCODING_KOI8_U     -  KOI8-U, a variation of KOI8_R modified to include glyphs for the
                                                       Ukrainian language, these glyphs are missing in KOI8_R

  FONTENCODING_KOI8            -  KOI8 ??
  FONTENCODING_RUSSIAN    -  the same
  
  
Here are my questions:


1) What is FONTENCODING_KOI8 here? KOI8 is just a family of charsets, including KOI8-R and KOI8-U.

2) Why is ISO_8859_5 called Cyrillic in FXFontDialog? This is not quite evident for a Russian speaking
    user that Cyrillic _is_ ISO 8859 5, and not CP1251 or whatever?
  
3) The charset used in Windows for Russian is CP1251. It is missing in the list of encodings in FXFont.h,
     but I found out, to my great astonishment, that FXFont objects created with encoding = 5 
    (FONTENCODING_ISO_8859_5 or  FONTENCODING_CYRILLIC) render text written in CP2151. 
    Evidently fonts created are CP1251 fonts?..    Or is there something I am missing?
   
4) If I want to use FXFontDialog under Linux to choose some KOI8-R font, I choose "Russian" in Character Set
    dropdown list. FXFontDesc objects returned by FXFontDialog in this case have encoding set to 17, that is
    FONTENCODING_KOI8 or FONTENCODING_RUSSIAN. The list of font families shown in FXFontDialog has just 2 families,
    though I have far greater number of KOI8-R fonts. I can view them in, say,  gtkfontsel. Or I can even create
    an FXFont object with encoding set to FONTENCODING_RUSSIAN and face set to "helvetica", though helvetica
    is not shown in the list of font families in FXFontDialog with "Russian" in Character Set.
