Subject: [PATCH 1/2] unittest: cannot use bytes regexes

>>> from unittest.case import TestCase
>>> c = TestCase()
>>> with c.assertRaisesRegex(Exception, b"x"): 1/0
...
ZeroDivisionError: division by zero

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/unittest/case.py", line 274, in __exit__
    if not expected_regex.search(str(exc_value)):
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
