I find these 'buffer interface' error messages to be the most confusing error message I get out of Python3 no matter what context they show up in. I have no idea what they are telling me. That issue is more general than transform/untransform, but perhaps it could be fixed for transform/untransform in particular.
I agree. "buffer interface" is a technicality that the Python user doesn't do about (unless (s)he also writes C extensions). How about "expected a bytes-compatible object"?
Regards
Antoine.
