I've noticed that when I enter some Russian text and try to
upper-case it, it does not get changed...
Case manipulation of internatinoal characters has been introduced to
XEmacs 21.4, so if you're not using that (or newer), it won't work.
By default we provide only the case-tables for Latin character sets.
If you want to provide the case table for Cyrillic, which I encourage
you to do, please take a look at how it's done in `mule/latin.el' and
add something similar to `mule/cyrillic.el'.
As far as I know, FSF Emacs handles this ok.
In that case, we can snarf FSF case conversion tables and incorporate
them into cyrillic.el.
