Either I misread, or you did: I thought that's exactly what Christoph was
saying, that iconv_* functions will be slower because they basically do
convert-process-unconvert rather than having implementations for each
encoding. 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.
