Does anybody know if VersaMail is able to handle different character encodings?

I have never been able to successfully send a message in anything but ASCII. I would like to send in CP1251 (cyrillic). I can successfully write on my Treo using this code page but when massage is sent and received it only contains question marks. However, when I receive messages encoded with CP1251 sometimes they show up normally and sometimes as question marks as well.

Any ideas?
