 I've got an international domain with an Ø in it (lets say it's
 kjøpting.no) and it works mostly great, except from some truly annoying
 admin redirects. It redirects to the domain, just without the IDN
 charachter.

 For example, when you try to log in to the admin interface (at kjøpting.no
 /wp-login.php) it tries to access kjpting.no/wp-admin instead of
 kjøpting.no/wp-admin. If you add the ø to the URL, you get access.

 It's the same for a lot of stuff like after installing plugins. It's
 possible to work around it by adding the IDN-charachter manually, but it's
 quite annoying and shouldn't be like this.
