Currently io.open_code (added in Python 3.8) only accepts str arguments. As per PEP-519, it should probably also accept PathLike. It might be worth extending it to accept bytes as well, both for convenience and because documentation claims it should be interchangeable with open(path, 'rb').

This seems to be a duplicate of https://bugs.python.org/issue39691

Dup of bpo-39691

As per PEP-578, open_code only accepts an absolute path as a str. The other issue will be used to update the docstring.
