Joe's right; Mudcat will not automatically display a Cyrillic font, but if someone posts lyrics in a Cyrillic font and lets you know which one they used, you can probably tease your browser into displaying it correctly.

Just to see if this is correct, here is a simple Russian word (= "thanks!") in three common Cyrillic encodings (Windows, KOI8-R, and Unicode):

1: Ñïàñèáî! (Win)

2: óÐÁÓÉÂÏ! (KOI8-R)

3: Спасибо! (UTF-8)

Try your Encoding menu and see if any of these work for you.
