How to sort respecting german umlauts

Hey there, I am sorting a structure, but ร„ comes after Z, how to include german umlauts?


I actually think this is broken. After some research, I think that it seems to be a change in the toolkit collection class introduced in 2.4.1 that results in sorting not respecting umlauts.


I have noted this for 2.5.9. Just reverting the commit wonโ€™t lead to a proper result though, but I will try to find a better fix. :slight_smile:
