Thanks Martin, I actually have read that page before.  The part that
confuses me is the line:

h = Header('p\xf6stal', 'iso-8859-1')

I have tried using:

h = Header('  ', 'GB2312')

but when I run the code, I get the following error:

UnicodeDecodeError: 'gb2312' codec can't decode bytes in position 2-3:
illegal multibyte sequence

Is there something I need to do in order to encode the Chinese
characters into the GB2312 character set?
