With your terminology, three types: char, non-NUL-text, encoded-text
(e.g. what happens with ord('ab'))
That's pretty silly, considering that these are all one Python type,
and TypeError is raised into Python code. Obviously it can't change,
because of historical reasons, but documenting it would be
straightforward and helpful. These are not errors you can just infer
will happen, you need to see it via documentation, reading the source,
or experimentation (and re experimentation, then you have to establish
whether or not this was an accident or deliberate).
