Comment (by mitjajez):

 Can't find how to make a patch here, but i belive we need do add
 '''idn_to_ascii''' function [http://php.net/manual/en/function.idn-to-
 ascii.php php > 5.4.0]
 {{{
 $domain = idn_to_ascii($domain);
 }}}
 on line [https://core.trac.wordpress.org/browser/tags/4.3.1/src/wp-
 includes/formatting.php#L2422 #2422 in wp-includes/formatting.php]

 and later
 {{{
 $email = implode( '@', array($local, $domain));
 }}}
 on line [https://core.trac.wordpress.org/browser/tags/4.3.1/src/wp-
 includes/formatting.php#L2446 #2446 in wp-includes/formatting.php]
