encodingis an array or comma separated list of character encoding. See supported encodings.If
encodingis omitted ornull, it returns the current character encoding detection order as array.This setting affects mb_detect_encoding() and mb_send_mail().
mbstringcurrently implements the following encoding detection filters. If there is an invalid byte sequence for the following encodings, encoding detection will fail.UTF-8,UTF-7,ASCII,EUC-JP,SJIS,eucJP-win,SJIS-win,JIS,ISO-2022-JPFor
ISO-8859-*,mbstringalways detects asISO-8859-*.For
UTF-16,UTF-32,UCS2andUCS4, encoding detection will fail always.
