I recommand PR 3940, as it's simple, and as I'm still unable to fix issue32200 with PR 4069 (I still don't understand how to write those latex macros).

I'm open to follow the discussion about PR 4069, if one find a nice documentable reproductible protocol to update the list of latex macros to allow for a new character to be added.

Please not the french and japanese documentation may still fail (French should succeed with xelatex, japanese will still fail), which is expected, it's the origigin of PR 3940 and PR 4069, I'm still working on it, also see: https://github.com/python/docsbuild-scripts/pull/34.
