Florian,

I think this is to do with the Content-Type header from your client.
This defaults to URL Encoding, so either use percent notation for
these special characters, or even more simply, specify JSON encoding.
See my full explanation on the ticket comments:

(BTW I could not see any difference between package creation and editing.)
