note 103805 added to function.mb-convert-encoding

I was just wondering if mb_convert_encoding() calls mb_detect_encoding if the "from encoding" field is left blank? It seems a bit improper, although trivial, to write: $encoding = mb_detect_encoding($my_str, "auto"); $converted_str = mb_convert_encoding($my_str, "UTF-8", $encoding); When it seems that this would do the same thing: $converted_str = mb_convert_encoding($my_str, "UTF-8"); Am I correct in thinking these are equivalent?
