in python 2 str and unicode were much more comparable. On balance I think just
reversing them ie str --> bytes and unicode --> str was probably the right thing
to do if the default conversions had been turned off. However making bytes a
crippled thing was wrong.

I dislike the current model, but that's because I had a lot of stuff to convert
and probably made a bunch of blunders. The reportlab code is now a mess of hacks
to keep it alive for 2.7 & >=3.3; I'm probably never going to be convinced that
uncode types are good. Bytes are the underlying concept and should have remained
so for simplicity's sake.
