Mbstring Requirement

[matthewknill]

I read that Mbstring is not required for this package, however, I run in to the following error (I don't have the Polyfill either):

<b>Fatal error</b>:  Uncaught Error: Call to undefined function Symfony\Polyfill\Mbstring\iconv_strpos() in /var/www/html/vendor/symfony/polyfill-mbstring/Mbstring.php:536

afaik, it only uses the function if it is defined

                if (\function_exists('mb_strpos')) {
                    if (\mb_strpos($haystack, $needle) !== false) {
                        return true;
                    }

@jorgecc why am I getting the error above then?
