I have little knowledgable about servers and the way they translate different language characters. To me I would try and track down where the characters are being changed and go from there. Maybe putting a Trace on the flash form, if it's okay there move onto the IIS server. I'm stretching here, but maybe see if the font in your email application reads those characters. Thats about all I can suggest, sorry. You might also be able to find some info on this at flashkit.com.
