This is not a bug. You specified LC_CTYPE = "C", so upper/lower case
conversion converts only ASCII letters. You need to specify a Russian
locale if you want case conversion to work on Russian letters.
Now having said that, I'm pretty sure that UTF8 locales are completely
broken on OS X, so that this wouldn't work even if you had specified
the right locale. But that's Apple's fault; there's little we can do
about it. I believe locale ru_RU.ISO8859-5 (with the matching encoding)
would behave sanely on OS X, if that's an acceptable fix for you.
