Comment:

 Nevermind, cancel the patch, it's too simplistic, it just bypasses the
 location ascii regex

 It would be nice if we could assume that if the user specified siteurl was
 the same as the actual location that everything was ok but we probably
 can't.

 I'll leave the patch here, so it's easy to see what the issue is.


 boils down to 2 issues.

 1. the native php header function does not support IDN names.[[BR]]
 2. WordPress needs actual support for IDN names, something like
 idn_to_ascii
    (if we had the above, we could still use the existing ascii
 preg_replace, just run the idn_to_ascii prior)

 there are several IDN libraries around, most are GPL'd, I don't mind
 adding one but I'm
 probably not the right person to make that call.
