Well, for me just appeared a lot of ??? chars. But, anyway, I guess it could be a browser compabitlity question, or something like that. There are posts where any cyrillic word is correctly shown, and there are times that not.
I have configured jforum, with the assistance of some nice guys here, to work well under any character encoding, and, afaik, it is working well, specially if you set the encoding to your country ( like big5, for example ) than the "generic" utf-8, like I use here in jforum.net
