Dynamic text, and missing characters

programming flash
1

Importing text from a external text.txt works just fine, but;
I can not get Flash to understand å ä ö (yes, Swedish characters!) It does not work using html encoding:

å
ä
ö

So how to solve this? I need to use those characters, å, ä and ö.

the correct capitalization is System.useCodepage=true;
