Comment:

 Honestly, I feel this is attributable to a bug in php itself
 http://bugs.php.net/bug.php?id=45657 (they of course disagree)

 so, the (ugly) work around (acceptable?) is to use a html meta redirect.

 If we could count on a idn_to_ascii method being available in a typical
 WordPress environment
 then 'header' would work. (but I doubt we can)

 //(PHP 5 >= 5.3.0, PECL intl >= 1.0.2)[[BR]]
 //$location = idn_to_ascii($location)


 The included diff is one approach that would resolve the issue.

 this fix assumes that the domain name they wish to use
 is set in general settings (wp-admin/options-general.php) as WordPress
 address (URL)


 Another possible approach would be to add a (optional) field to the wp-
 config.php file

 Something like 'IDN name', one could put the punycode version of the url
 here.

 then if that variable is set, make sure the header redirect would use it.

 # support for IDN names[[BR]]
 define('IDN_AS_PUNYCODE', 'xn--domne-ura.dk');[[BR]]
 domæne.dk -> (as punycode) -> xn--domne-ura.dk
