Unfortunately, the manual[1] is not explicit about that issue, 
but I assume that FILTER_VALIDATE_EMAIL validates according to
RFC 5322, which does not cater for IDNs.  If so, this might be
regarded as "documentation problem".

This bug report is related to request #65385[2].

Description:
------------
Hello,

If I use the following script, the filter_var return always false, but the 
Domain is possible.

It is possible to fix it, that Domains with ÜÖÄ are exepted?

Thanks you in advance!

Test script:
---------------
<?php
if(filter_var('example@öko.de', FILTER_VALIDATE_EMAIL))
{
        echo 'ok';
}
else
{
        echo 'fail';
}
?>
