I stoped using polish fonts so people can see letters rather than bunch of question marks
it's a big mistake, I tell you.
this site displays Polish words correctly (even in Interner Explorer 6.0),
the problem you are talking about is rather connected to poor HTML-coding, this site seem to support the fonts well, it's like with Chinese - on some sites all you can see is a "bunch of question marks", but on other you can actually see the text correctly
