Comment (by ysalame):

 ugh... sorry. I actually pasted the email that was sanitized.

 The test I made was

 {{{
 $target_email = 'dummy-üñîçøðé.y.!#$%@üñîçøðé.gmail.com';
 echo $target_email.'<br>';
 echo sanitize_email($target_email).'<br>';
 echo 'is_email : '.is_email($target_email);
 }}}

 with return as

 {{{
 dummy-üñîçøðé.y.!#$%@üñîçøðé.gmail.com
 dummy-email.y.!#$%@gmail.com
 is_email :
 }}}

 The unicode characters were all removed. For international emails this can
 be a real problem.

 ps. I actually used the Wiki page you sent as a base for my ticket. I
 tried a mix of one of the last examples in the "Valid email Examples"
 list.
