You are not alone... This is an ages old issue with Flash, but it does work. I have the same setup as you do and the same problem using Flash 8. See my forum post "Flash does not display extended characters". I have provided much detail in my setup, maybe you have missed somethin I mention - it may fix your issue.
If the setup in my post fixes your issue, I hope you could assist me.
If I get an answer I'll help you as well. If you get an answer, please share with me.
