UTF8 should be supported in regex

$parts = preg_split(
            '/([^0-9,a-z,A-Z$_:])/i',
            $identifier,
            -1,
            PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY
        );

I run into problem because pattern '/([^0-9,a-z,A-Z$_:])/i', doesn't support utf8.

I think pattern modifier 'u' should be added. '/([^0-9,a-z,A-Z$_:])/iu'
