Input encodings

Several Cyrillic code-pages are widely used. Currently, L^ATEX contains support for 20 Cyrillic input encodings (some of which are variants of each other).

• cp855 -- the standard MS-DOS Cyrillic code-page.

• cp866 -- the standard MS-DOS Russian code-page. Several code-pages very similar to this are also supported (the differences are all in the range 242-254).
  • cp866av - the `Cyrillic Alternative' code-page (an alternative variant of cp866);
  • cp866mav - the `Modified Alternative Variant';
  • cp866nav - the `New Alternative Variant';
  • cp866tat - an experimental Tatarian code-page.

• cp1251 -- the standard MS Windows Cyrillic code-page.

• koi8-r -- a standard Cyrillic code-page widely used in UNIX-like systems for Russian language support that is specified in RFC 1489. The situation with koi8-r is somewhat similar to that for cp866: there are several similar code-pages which coincide for all Russian letters but add some other Cyrillic letters. The following are supported:
  • koi8-u - for Ukrainian;
  • koi8-ru - this is described in a draft RFC document specifying a widely used character set for mail and news exchange in the Ukrainian internet community, as well as for presenting WWW information resources in the Ukrainian language;
  • isoir111 - the ISO-IR-111 ECMA Cyrillic Code Page.

• iso88595 -- the ISO 8859-5 Cyrillic code-page (also called ISO-IR-144).
• maccyr -- the Apple Macintosh Cyrillic code-page (also known as Microsoft cp10007) and macukr, the Apple Macintosh Ukrainian code-page, very similar to the Cyrillic code-page.

• The Mongolian code-pages: ctt dbk mnk mos ncc mls. These code-pages were taken from Oliver Corff's `MonTEX' package (available at CTAN:language/mongolian/montex). Since the T2* encodings support the Mongolian Cyrillic script, it is convenient to have support for Mongolian input encodings as well. Pointers to documentation for these code-pages will be much appreciated.
