Thank you Yejun.
I have now realized that the problem was that I was mixing strings and
binary bytes in the response. I started with a string header, which
must have initialized the StringIO to ASCII encoding. If I remove that
header, I don't have any errors. I'll change the string header to the
HTTP headers section, so I do not have to mess with mixing strings and
binary data.
