A classic problem is the name of the bridge between sweden and denmark
that is Öresundsbron, that can also be spelled Øresundsbron. And btw,
have the URI http://www.oresundsbron.com/, or http://osb.oeresundsbron.dk/
or...
If they are offended? No I do not think so, but people in Sweden think
the spelling is Öresundsbron, and the spelling for a danish person is
Øresundsbron.
Note if you click on the flags they call themselves Øresundsbron in
Swedish, Norwegian, Danish and English, but Øresundbrücke in German.

This is what I have seen at least some of them doing. I.e. being
interested in having the *same* mappings and rules etc. All in all to
help the user.
This is why I am not so nervous of IDNA200x not having mapping as part
of the standard. The mappings you all ask for will be defined. You
have yourselves started!!! Registres have written lots of text
themselves. Etc.
