With a capital ? in the middle? That's unusual.

If your database is using latin-1, German and French names will work, 
but Croatian and Polish names often won't. Not to mention people using

So G?nther and Fran?ois are ok, but Boles?aw turns into Boles?aw and 
don't even think about anybody called ???????? or ????.
