For the record, it never aimed to support punycode. One has to convert them first.

This doesn't seem to be fixed. Please reopen.
dean@ernie:~$ php -r "var_dump(filter_var('fred@bücher.ch',
FILTER_VALIDATE_EMAIL));"
bool(false)

This has since been fixed, and works in the current 5.2 and 5.3 releases.

Description:
------------
The filter FILTER_VALIDATE_EMAIL does not accept IDN domain names, so valid email addresses are not
accepted, the punycode version works.
I know the check for this is a little bit complex, because the allowed chars in the domain name
depend on the TLD.
I think the current behavior is okay as default, but there should be an option to allow IDN domain
names.
Reproduce code:
---------------
<?php
var_dump(filter_var('test@tätärätää.de', FILTER_VALIDATE_EMAIL));
var_dump(filter_var('test@xn--ttrt-loabbba.de', FILTER_VALIDATE_EMAIL));
?>
Expected result:
----------------
string(...) "..."
string(...) "..."
Actual result:
--------------
bool(false)
string(...) "..."
