I think I have pretty much the same problem. When I enter a german city with an “umlaut” like “Nürnberg” for example, your plugins encodes it to “N%FCrnberg”
Changing the parameter you mentioned in the post above, doesn’t resolve the problem (i changed it to de of course :).

I would really apreciate it, if u could point me (us) into the right direction on how to fix that problem.
Kind regards
