PyUnicode_AS_UNICODE removed from Python 3.12 which is now the current version in Fedora Rawhide.

See the following for details:
https://docs.python.org/3/c-api/unicode.html#c.PyUnicode_AS_UNICODE

It mentions moving to PyUnicode_KIND but does not give any examples of how to port the code.

I tried to check if this has already been addressed in git but the breakout of the projects makes it too confusing where to look.
