German language / Umlaute

[pereh]

Hello,

I am new to UR and just doing my first steps, and I have a question for which I could not find an answer in the doku or the forum.
Most of the documents I use are in German language, so there are a lot of special characters like Ä, ä, Ö, etc. (Umlaute). Not only don't they appear in the normal text display of the items, but the words containing such characters are also ignored when building the automated keywords. That way, searching might sometimes become pointless.
Is there a way to tell UR to handle these characters like normal ones?

Thanks for your help,
Peter.
