18952,AJAX calls to IDN don't work in IE and Opera,SergeyBiryukov,nacin,"In jQuery 1.5+, AJAX requests on sites with IDN domains don't work in IE 8 or 9.

On Edit Post screen, adding a new category results in JS error:
{{{
Message: 'parsed.responses' - is null or not an object
Line: 311
Char: 4
Code: 0
URI: http://домен.рф/wp-admin/js/post.dev.js?ver=20110524
}}}

On Categories screen, adding a new category silently fails.

According to [http://bugs.jquery.com/ticket/8419#comment:3 jaubourg's comment] in jQuery bug tracker, the request is considered cross-domain and, since IE doesn't support cross-domain requests, AJAX won't find a suitable transport and bail out. The ticket only refers to IE 8, but I've checked this in IE 9, and it seems to show the same behaviour.

A workaround suggested there is to use unencoded domain name or strip it completely.",defect (bug),closed,normal,3.4,I18N,3.2.1,normal,fixed,has-patch dev-feedback,
