There seems to be a problem on macOS for Python 3.10 (installed with brew):

******************** Terminal ($? = 1) ********************
Traceback (most recent call last):

    return _setlocale(category, locale)
locale.Error: unsupported locale setting

It seems that this is an old problem and that in the past the Sphinx devs used a workaround to silence this error: sphinx-doc/sphinx#5724.
However, recently, this workaround was removed: sphinx-doc/sphinx@c7d7f29.

I can also see that the associated locale problem was closed in the cpython repository as solved: https://bugs.python.org/issue18378#msg215215 python/cpython#62578.

Not sure why the error is showing up...

Now there are some errors with Python 3.12 due to the removal of the imp module, used by the pytest-shutil and pytest-virtualenv plugins...

man-group/pytest-plugins#219

It is been a while that I wanted to remove these plugins... they seem always to bring some sort of complication. Setuptools uses jaraco.envs.VirtualEnv to implement its own venv fixture: https://github.com/pypa/setuptools/blob/b545fc778583f644d6c331773dbe0ea53bfa41af/setuptools/tests/fixtures.py#L104

It seems that replacing:

-  LC_ALL: C.UTF-8
-  LANG: C.UTF-8
+  LC_ALL: C
+  LC_CTYPE: UTF-8
+  LANG: C

Fixes the specific macOS problem (C.UTF-8 is not POSIX).
@FlorianWilhelm do you think this is the correct solution?

If you agree, I can go ahead and also modify the Cirrus templates.

Let's add this one for now... we can revert it later.
