I just applied that patch, but still my members with german Umlauts are printed like Stefan Hülzer
I'm going to leave it as above because my stupid MUA translated the MIME word into UTF-8 even though it should not (MIME words should not be recognized in content, only in headers), and it made me laugh. You're not crazy -- it was a MIME word in your mail, of course. It's all the mail programs that are nuts!
I suspect what's happening is that the MIME words are in the backend database in the display name field, when they should just be UTF-8 strings. If so, you should be able to fix the existing ones with a withlist script. I haven't written one in a while and it's past 2am here so please forgive me for getting some sleep. I'll check mail tomorrow if you need help.
Happy New Year!
