Continuing the discussion from Please replace German umlauts in URLs with their respective digraphs:
I love this feature a lot, thanks to @gerhard at this point! But (there is always a but…) I just saw, that umlauts aren’t handled correct in the bagde urls. That isn’t a big deal, but I think if we do it, we can do it also for the badges. Don’t know if that is hard to implement. Maybe a feature for some time in the future.
