improve handling of uppercased german Umlauts (Ä to Ae instead of AE)

[thyseus]

Why?

It is much more common that a german word containing uppercased Umlauts will be transformed with a small second character:

Äpfel -> Aepfel Öl -> Oel

perhaps this is also the case in other languages. What are your opinions about this ?

I agree this might be a common use case, but it might not be the intention of everyone using it. It could be a passable option or just be up to the user to capitalise their strings as they desire.
