I will post the result.

This is a general question about what Cyrillic language environments
Emacs should have.  Please give a suggestion.  This is the current
situation about locales and languages:

be in mule-cmd.el maps to language environment "Belarussian" (the right
spelling is Belarusian, not Belarussian).  There is no such language
environment in Emacs.  The locale be_BY is for CP1251 but Emacs doesn't 
support CP1251 in cyrillic.el.  I can make the necessary changes about
that but AFAIK Dave Love does something similar and I'd better contact
him.

Acording to Alexander Mikhailian (the author of "Belarusian-HOWTO") ISO
8859-5 is better supported than CP1251 and thats why Emacs should
support also Belarusian+ISO-8859-5.  I guess this means two languages
environments for Belarusian: Belarusian-CP1251 and Belarusian-ISO?

bg in mule-cmd.el maps to language environment "Bulgarian" which also
doesn't exist.  The locale bg_BG is for CP1251.  Bulgarian GNU/Linux
users have always used CP1251, even before XFree4.0.2 (the first version
that supports this encoding).  Two completely different keyboard layouts
are used in Bulgaria.  This has been discussed already
<http://mail.gnu.org/pipermail/bug-gnu-emacs/2002-January/009497.html> I
think it is better to have two language environments Bulgarian-BDS and
Bulgarian-phonetic.

mk (Macedonian) in mule-cmd.el maps to "Latin-5".  The locale mk_MK is
for ISO 8859-5. The most closest language environment is "Cyrillic-ISO",
but it uses Russian keyboard.  If you agree I will make language
environment for Macedonian, or else that will be "Cyrillic-ISO".

ru in mule-cmd.el maps to "Latin-5".  That definitely should be
"Cyrillic-ISO".

tg (Tadjik) in mule-cmd.el maps to "Cyrillic-KOI8-T".  There is no such
language environment in Emacs, but I can make it.  KOI8-T has to be
added in cyrillic.el.

uk (Ukrainian) maps to language environment "Ukrainian".  There is no
such environment in Emacs, but I can make it.  KOI8-U has to be added in
cyrillic.el.

I will see what I can do.

There are no problems in text-mode.  Emacs beeps not only to
alphanumeric characters but also for xkeysyms like "ISO_Next_Group".
