When I edit my user profile and enter my affiliation in German, i.e. "Universität Gießen", I get the following error, due to the use of ä and ß: Is there an easy way to extend the DB schema to allow for these characters? If not, I think we need more speaking error messages to let the user know what the actual problem is.
