     * - ASCII

     * it will never match ASCII, because UTF-8 is a superset of ASCII.
     * Similarly, SJIS and EUC-JP frequently match UTF-8 strings, so you should
     * check UTF-8 first. SJIS and EUC-JP seem to work either way, but SJIS is
     * more common so it should probably be first.
     *
     * While you're free to experiment with other charsets, remember to keep
     * this behavior in mind when setting up your char_encodings array.

     *
     * This is *NOT* reliable and should not be trusted implicitly. Since it
     * works by triggering and suppressing conversion warnings, your error
