Note that not all these encodings are good to be used as TeX internal
encodings. The T2* and X2 TeX cyrillic encodings were created because
of this. In particular, any TeX text internal encoding (including
cyrillic) must follow some restrictions for T* encodings to be
"multilingually safe". So, is there really a need to register a lot of
TeX cyrillic encodings? [note that _input_ encodings such as
iso-8859-5, koi8-r, cp866, cp1251 and others are all supported via the
inputen mechanism]

Next, we should register all four encodings: T2A, T2B, T2C and
X2. What do you think are the best names for them in the fontname
scheme? Maybe 6t, 6u, 6v, 6x respectively?
