requests.Session() how do you set 'replace' on the encoding?

It looks strange that you can set "s.encoding" after you have
called "s.get" - but, as you apparently get an error related to
the "gbk" encoding, it seems to work.

I see the following options for you:

  *  you look at the code (of "requests.Session"),
     determine where the "s.encoding" is taken care of and
     look around whether there it also support a replacement strategy.
     Then, you use this knowledge to set up your replacement.

  *  you avoid the "unicode" translating functionality of
     "requests.Session". If it does not immediately supports this,
     you can trick it using the "iso-8859-1" encoding (this maps
     bytes to the first 256 unicode codepoints in a one-to-one way)
     and then do the unicode handling in your own code -- with
     facilities you already know of (including replacement)

  *  you contact the website administrator and ask him why
     the delivered pages do not contain valid "gbk" content.
