Text Auto-Complete field and swedish letters ÅÄÖ

Hi,
I have a text field and there I can type Swedish letters with no problem, but if I change it to Text Auto-Complete it is looking up the values correctly from database (looks OK in the list). But when I save values to database, the Swedish letters are scrambled! :confused:

check your database tables charset, also check if you insert those letters in db directly from phpmyadmin? did you select the right unicode in the connection settings?
