Case-sensitive for slugs?

Is there an easy possibility to use case-sensitive for slugs?

Especially for other languages than english, where there are often uppercase words with a different meaning (or grammar) of the lowercase version, it would be quite nice to have this function.

One silly example in German: “feier” (imperative of “to party” like in “Let’s party!”) is different to the noun “Feier” (the party itself).

Actually I want an automated generated field (similar to slugs, if it’s too complicated to modify it) like Wikipedia is using for its names/slugs in the url, which is obviously case-sensitive.

Any ideas?
