Please let me know which mailing list address to use if I have sent this to
the wrong list.
filter_var does not properly validate emails with international characters.
For example, this returns FALSE:
var_dump(filter_var("Pelé@example.com", FILTER_VALIDATE_EMAIL));
Are there any plans to implement proper validation of email addresses as
described in RFC 6530?

Hi,
There was a discussion a while back about Internationalized Domain Name
support in FILTER_VALIDATE_URL [1], and I believe there was a concern
that since not all systems would accept the wider format, allowing them
through the existing filter might be unhelpful. This is particularly
true in the case of internationalized e-mails, since if I understand it
correctly it's an "all or nothing" system, rather than one with a
compatible fallback like the "punycode" notation used in domains.
The most useful would probably be to add a new filter type which
accepted the new format, so that users could choose to accept what they
know they can process. If you know of or can create a succinct validity
test (e.g. a PCRE-compatible regex) it ought to be fairly easy to add;
the existing implementation is here for comparison:
