the sort order in tables in dewiki should use uca-de-u-kn.
as of now „Č“ follows "Z", but it should sort as same as C
Example from "Österreichisches Wörterbuch" https://en.wikipedia.org/wiki/%C3%96sterreichisches_W%C3%B6rterbuch 42.Auflage: S. 151-S.152
Cs → Csarda → C-Schlüssel → ČSFR → CSI → ČSR → ČSSR → ct → CT → c. t. → Cu
@Boshomi Please add to the description a "use case" page with:
That will allow to test the fix to the JavaScript sorting code.

Per T128806: Switch German Wikipedia to uca-de category collation, this would need some consensus. I'm going to merge this task into that one.
