In that case you're using the wrong locale (ie, not russian unicode).
Check "show lc_ctype".

Or [ checks back in thread... ] maybe you're using the wrong operating
system.  Not so long ago FreeBSD didn't have Unicode locale support at
all; I'm not sure if 6.2 has that problem but it is worth checking.
Does it work for you to do case-insensitive russian comparisons in
"grep", for instance?
