Hi,
I use osclass in version 356 and german language. If set permalinks active, the search doesn't rewrite the keywords. In Germän we hav Ö, Ä, Ü, ß (ö, ä, ü) which should be OE, AE, UE, SS (oe, ae, ue).
I'm not sure but I think in older versions there were no problems with umlaute.
Anybody an info or Tip?
Best regards,
pare
