So mb_strlen will always be faster than iconv_strlen. iconv() vs mb_convert_encoding() doesn't have the same penalty. It seems quite plausible that a library dedicated to converting charsets would be more optimised for that job than a single function in a larger library mainly focussed on working with one charset at a time.
