I am trying to make a form validation using preg_match and it fails.
I think it is because the input is in Greek. I have made this script:
$str = "ΕΕΝ 5196";
$pattern = "/^[[:alnum:]\s\-\,]*$/u";
to test preg_match's behavior and when the above string has Latin
characters the pattern matches when it's in greek. Can someone explain
this? Is there a workaround?
PS all are in UTF-8.
