Well, the thing is that ru_RU.KOI8-R is indeed needed. If I start X
without it, I will not be able to type in cyrillic letters in the xterm.
Also many programs switch to russian localisation mode when started with
LANG set. The fact that Xterm behavor is clearly influenced by the value
of LANG makes me think that it is indeed supported by X (also that's what
I get from reading stuff on the web). The only case when I do see the
above message about ru_RU.KOI8-R not being supported is when I start
Linux apps (linux-jdk, linux-netscape etc). I'll try to look at the code
but chance that I'll figure something out are rather slim :(
I've just checked native jdk1.1.8. It doesn't allow to enter russian
characters, doesn't complain about locale and doesn't throw any
exceptions.
