Hi again,
Sorry for the delay, but I didn't see your response until a few moments ago.
I've just downloaded your test file and sadly it doesn't seem to be doing all that well
Even some of the languages that it claims to have menu support for (e.g. Dutch and Polish) have some small errors. Russian is not displaying at all, but that's not surprising.
I'd be happy to try adding some font sets if anybody knows where I could download some from. I don't have any decent information about how to use them, but there is an existing folder for fonts and it's easy enough to drop them in there. Getting them to work well might be another story....
