FILTER_VALIDATE_URL returns false when it should return true

[lolcatw]

Description

The following code:

<?php
var_dump(filter_var("https://www.bug.com/wp-content/uploads/2022/09/Famous-Internet-Man-512-×-512-px-1.png", FILTER_VALIDATE_URL));

Resulted in this output:

bool(false)

But I expected this output instead:

string(x) <url here>

This seems to be due to the fact that the URL contains -x-.

Many thanks.

You need to urlencode for the × character. https://3v4l.org/tnV99 Modern browser will replace percent encoded characters for usability. See https://stackoverflow.com/questions/2742852/unicode-characters-in-urls for more information.
