(You might consider going to ASCII-only characters for file names - e.g. using a suitable Cyrillic-to-Latin transliteration - to avoid the problems that tend to come up with multi-byte characters in file names.)
What a... peculiar thing to say. There are no problems with multi-byte chars in file names. There might be problems with things truncating file names, and transliteration is a really bad way to fix that.
