 Replying to [comment:8 hakre]:
 > URLs per definition can only conain ASCII chars. If clean_url() removes
 non ascii (7bit I hope) chars, that's fine. Please use the PUNYCODE
 notation of your domain instead of the UTF8-representation.

 I believe that Wordpress has enough international usage to warrant proper
 IDN support.
 It seems sub-optimal for Mr/Mrs. Müller to have to send users to their
 website: xn--mller-kva.com, rather than müller.com

 ''An IDNA-enabled application is able to convert between the
 internationalised and ASCII representations of a domain name. It uses the
 ASCII form for DNS lookups but can present the internationalised form to
 users who presumably prefer to read and write domain names in non-ASCII
 scripts such as Arabic or Hiragana. Applications that do not support IDNA
 will not be able to handle domain names with non-ASCII characters, but
 will still be able to access such domains if given the (usually rather
 cryptic) ASCII equivalent.'' -
