Hi Jigal

Thanks for answering. I tried what you suggest, but it changes nothing. 
Maybe I don't quite get it.

Are you saying that its not possible to set up a multi-language TYPO3 
site and at the same time do sorting on danish characters?

I found out that if I change the field collation of a field I want to 
sort on, to utf8_danish_ci, then the sorting works.
