#41 — umlauts (special charackters) in foldernnames fails

In german (i think in other languages as well) we have special cahracters like ä, ü, ö, ß and so on. In normal plonfolders it is possible to use these charackters without problems. When i changed the folder to a cild site, i got the following error, when i try to add an item to this folders or to change it.

Traceback (innermost last):
