Martin von L?wis kindfully pointed out Chinese codecs at
ftp://freebsd.sinica.edu.tw/pub/ycheng/python/ChineseCodecs1.2.0.tar.gz
in another post...

>how to my input is really encoded in gb2312?

If you know that it is "simplified Chinese" you are inputting, it's safe to
say you are inputting gb2312. On Windows, this is codepage 936. Run "chcp"
in your command prompt. This should yield "CP936" as your current codepage.
This of course only applies if you are using Windows 2000's native support
for non-unicode based applications. If you are using a layer on top of
Windows, you are on your own... If you are inputting "Traditional Chinese"
(which would yield "CP950" when running chcp), it's safe to say that the
encoding is "Big5".
