I get the impression this could be a little fiddly to fix (on python2 you want .encode('utf8') (probably)` but you get problems with bytestrings if you do this in python3.

Sorry for the long delay!!! As meanwhile Python 2 has reached end-of-life I prefer to drop any "support" for it.

Closing with repeated reference to Python 2 EOL, after way too much time...
