Optional Argument Validation Fails for ® about vies HOT 2 OPEN

Regex fix for ®

^[a-zA-Z0-9\s\.\-,&\+\(\)\/º\pL®]+$

from vies.

As a workaround for myself going forward I am now “precleaning” these optional arguments – stripping away everything which the regex will not accept as valid before I pass them to this library, e.g.

        $clean = function($s) {
            return preg_replace('/[^\p{L}0-9\s\.\-,&\+\(\)\/º]/u', '', $s);
        };

I think that will work fine for me, perhaps for others too.
