* denotes encodings usable also in regular expressions.

Any php.ini entry which accepts an encoding name can also use the values " auto " and " pass ". mbstring functions which accept an encoding name can also use the value " auto ".

If " pass " is set, no character encoding conversion is performed.

If " auto " is set, it is expanded to the list of encodings defined per the NLS . For instance, if the NLS is set to Japanese , the value is assumed to be " ASCII,JIS,UTF-8,EUC-JP,SJIS ".

Appart of this list, GB2312 encoding is also supported.
It is Chinese Simplified encoding which is now superseded by GB18030, but GB2312 is not in the list.
If you try to us it, the result will allright even if it is not in the list.

Use mb_list_encodings() to checc if an encoding is supported by mbstring before using its functions for it.
