IMO adding locale.getencoding() to Python 3.11 is not controversial
and is useful even if PEP 686 is rejected. This function was discussed
for 1 year (bpo-43510, bpo-43552, bpo-43557, bpo-47000) and there is
an agreement that there is a need for this function.

If someone explicitly opts in for the "locale encoding", it sounds
surprising that the locale (encoding) is ignored and that UTF-8 is
used if the Python UTF-8 Mode is enabled. I'm fine with this change.
If you want to always UTF-8... Pass explicitly UTF-8:
# no surprise, always decode file content from UTF-8
json_file = open(filename, encoding="utf-8")

I will not comment PEP 686 here. It's being discussed on Discourse:

* https://discuss.python.org/t/14737
