strlen() protected method

We cannot simply use strlen() for this, because it might be overwritten by the mbstring extension. In this case, strlen() will count the number of *characters* based on the internal encoding. A sequence of bytes might be regarded as a single multibyte character. Use elgg_strlen() to count UTF-characters instead of bytes.

        if (function_exists('mb_strlen')) {
            return mb_strlen($binary_string, '8bit');
        }
        return strlen($binary_string);
