Font config

[Oleg Goodyckov]

Hi!

I use GC under RedHat9.
While starting, it gives out next message twice:

The font "-adobe-helvetica-medium-o-normal--*-120-*-*-*-*-*-*" does not
support all the required character sets for the current locale "ru_RU.KOI8-R"
  (Missing character set "KOI8-R")

And then in register and in other places cyrillic text looks incorrectly.

So, can anybody tell me, which configs these fonts are indicated in and
how to indicate rigth fonts there?

Thanx!
If it is possible, please, answer me by e-mail, because I'm not subscriber
of mailing list.
Thanx again!

Oleg.
