I believe that content_encoding is only relevant to the received

If using mod_python.publisher and returning your page content as the
return value, add "req" as one of the function input parameters and do:

   def index(req):
     req.content_type = 'text/html; charset=UTF8'
     return "<html>....</html>"

Provided you are using mod_python 3.2.8, if the publisher function  
a Unicode string, then mod_python.publisher will automatically attempt
to fill out the charset in the content type header for you.

Some updates are made, but because they in source code repository copy
of documentation, you will not see them until next major release of  

Also, Nicolas, Jim and I all have limited time. Our job would be made  
though if users of mod_python would like to offer up the examples and  
where to put them in the documentation. Remember, our focus is not  
to be where your focus lies and so we wouldn't even think to update a  
bit of documentation unless it is pointed out to us specifically with  
of what to put in it to make it better.

Any documentation changes/enhancements can be logged at:


There is no point posting them just to the mailing list as they  
inevitably get lost.
If on JIRA, they have to be dealt with eventually.
