German sharp S uppercase mapping

[Giacomo Catenazzi]

I think you are taking the issue personally, and in a myopic view.

So you want to break many files? If you change the machine translation, 
you will have conflicting (and possibly disappearing documents), because 
filesystems in Windows (and default in macos) are case insensitive.

As people said: that it is a different case, which should be handled 
outside the machine translation.

You are speaking about legal documents, but in reality only on German 
legal documents, so as other said: it should be put in local casing. In 
Switzerland we do not want such legal distinction.

Switzerland uses it differently.
