IDNA here we go!

I guess that TYPO3 assumes domains names to be plain old ASCII.

I see thre solutions.

* Don't do any check against the domain name
* Allow for the 100 or so new chars (mind the charset of the BE!)
* Transform a domain name into an ACE label (punycode) on storage

The last option may be beefed up by a transformation back on display.
