You forgot to specify the page encoding, gb2312 presumably. If adding the
encoding does not help, I'd say the problem must reside on how you later
use row01 and row02 (your html page does not those variables for
anything). '中文' is the same as '\xd6\xd0\xce\xc4', and both javascript
and Python share the same representation for strings (mostly) so this
should not be an issue.

My PC is unable to display those characters, but I get "true" from this:

<html><head><META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset='gb2312'"><title> test </title></head>
<body><script
language=javascript>alert('中文'=='\xd6\xd0\xce\xc4')</script></body></html>

I did that: <META HTTP-EQUIV="Content-Type" CONTENT="text/html;
charset='gb2312'">, but it does not work. Alert('\xd6\xd0\xce\xc4') displays some "junks". I am thinking there may be some way to convert '\xd6\xd0\xce\xc4' to '中文' in the list with python before I generate the html page. As a result, when I open the html file with Vi, I can see '中文' directly instead of '\xd6\xd0\xce\xc4'. That will solve my problem. 

Any ideas?


Use charset=gb2312 instead of charset='gb2312'(remove single quotes).

I was able to display 中文 successfully with this code:

f=open('test.html','wt')
f.write('''<html><head>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html;charset=gb2312">
<title>test</title></head>
<body>\xd6\xd0\xce\xc4</body></html>''')
f.close()
