Flash multiple languages

first of all I wanted to apologize if this thread has already been opened, but I havent found anything for my needs sofar.
My concern is about different languages in flash slides.
Meaning I have to create programs where you have a lot of text involved and this has to be in multiple languages eg: german.
For example in german you have letters like Ö,Ä,Ü that cannot be displayed in flash (at least I couldn’t sofar figure out HOW).
Therefore I wanted to know if anyone has an idea how to do this? Possible I need a language pack for cs4 or something similar?
Would really apprechiate any comments/solutions.
Thanks in advance!
