Is this necessary? I thought in Python 3, the "utf-8" encoding was default?

Anyways, maybe the best bet would be to modify this function with an encoding argument and default it to None, which is the default in the underlying functions being called:

+1 to this. We might want to run through the uses of it and set it to utf-8 where it's used in demos and examples here though.
