* breaking things for one of the other charsets:
* - ASCII
* - UTF-8
* - SJIS
* - EUC-JP
*
* The order of the charsets is significant. If you put UTF-8 before 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 depends on the mbstring extension

* windows-125x and iso-8859-x which have practically undetectable
* differences because they use every single byte available.
*
