Review comment:
It would be really helpful here to explain what the AMQP limitations on
property keys are. I can't figure out from reading this code what the actual
point of the code is.

Review comment:
But if the above code is actually necessary for some reason, then this
line is no longer necessary. As in context it is just another way of saying
'pass'

Review comment:
Why is this even necessary? It's already a (perhaps subclass of)
unicode. won't encode just work directly?

Review comment:
I don't think converting py3 bytes is acceptable as binary is not a good
key (or is it?) it looks like in the previous code it would have triggered an
error - only py2 binary would have been converted.

Review comment:
I think you can leave this test as 'str' as it was before - it only
covers the py2 str (binary) case as py3 str is already covered above in
unicode, I guess you still need the decimal128 case still though.
