Liland,Cyrillic characters cannot be viewed by anyone who does not have a Cyrillic font installed on their computer. Since I have never had occasion to install such a font, I will never be able to see your Cyrillic characters, no matter what you do.
That said, however, there should be a way of using the <FONT FACE="something"> tag as a way of showing the Cyrillic characters to anyone who DOES have a Cyrillic font installed.
However, I don't know what the something ought to be. At a wild guess, something like font name,Russian/Cyrillic.
