Hello Wiktionarians,
A bug was reopened to "allow collation to be specified per category" in
Wiktionary (all languages are concerned).This would be a much better solution than to
create sort keys in every article and for every language.
Please vote for this bug to express your interest in this much needed feature:

Cheers,
