We have the same problems with Sámi characters: ŽžÄČáÃÅ Å Ä‘ÄŋŊŧŦ
The problem occurs in wires and member theme fields. The procedure for carrying the utf-8 characters to the database seems to be wrong. All characters are replaced with ‘?’ indicating that the fields do not handle utf-8 characters. Since the texts then get stored without correct characters in the database, all texts has to be re-entered to be corrected when the problem is fixed.
I think this is an extremly serious fault in Buddypress so far, and excludes us needing the utf-8 characters to use BP.
