UTF with German letters or looking for German market favorites

[phadda]

hm strange
i tested a little bit last days, like change the xml form to latin/iso from utf, but nothing happens. placed a lot of unicode html sequences and so on in the fav txt but nothing happens. everytime i get squares instead of the german letters ä and so on :/ i´m no xml guru, maybe the file format must have the xml extension instead of the txt? or maybe the pulldown format from the fav ingame should format as a utf character set?
are there no other ui designer with localaized problems? if i take a loot at the french letters, there are a lot of french only letters or russian and so on... maybe i try a post on the official eq2 forum, hopefully a ui dev read this post and give me some hints
