mb_detect_order() sets automatic character
encoding detection order to
It returns TRUE for success,
FALSE for failure.
encoding_list is array or comma separated
list of character encoding. ("auto" is expanded to
"ASCII, JIS, UTF-8, EUC-JP, SJIS")
encoding_list is omitted, it returns
current character encoding detection order as array.
Note: mbstring currently implements following encoding detection filters. If there is an invalid byte sequence for following encoding, encoding detection will fail.
Note: UTF-8, UTF-7, ASCII, EUC-JP,SJIS, eucJP-win, SJIS-win, JIS, ISO-2022-JP
For ISO-8859-*, mbstring always detects as ISO-8859-*.
For UTF-16, UTF-32, UCS2 and UCS4, encoding detection will fail always.
