The X2 encoding was designed to support all the above languages. Its name does not start with T because, for example, it contains no Latin letters (it is purely a Cyrillic glyph container); it therefore cannot be used in mixed-script documents along with the other T* encodings. Please consult Section 6.4 Naming conventions of the file fntguide.tex in the base L^ATEX distribution for details of the differences between L^ATEX font encodings and how they are named.

There are two other L^ATEX Cyrillic font encodings, OT2 and LCY, that are not included in the base L^ATEX distribution. The first is a 7-bit encoding (hence the O) developed by the AMS; it is useful for typesetting relatively small fragments of text in Cyrillic, using a Latin transliteration scheme. The other, LCY, is an 8-bit Cyrillic encoding which is not compatible with the requirements for L^ATEX T* encodings (hence the L); thus it is not suitable for typesetting multi-lingual documents, but it can be used in Plain TEX-based macro packages because it is an extension of OT1. These two encodings are supported by babel and by ot2cyr.
