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.
Making
open(path, encoding="locale")use locale encoding in UTF-8 mode (Python 3.10 used UTF-8)
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:

Hi, Pablo.
I just submitted the PEP 686 to the SC. https://github.com/python/steering-council/issues/118
In this PEP, I am proposing:
a. Small improvement for UTF-8 mode in Python 3.11 b. Make UTF-8 mode default in Python 3.13.
(a) is an important change for (b) so I included it in the PEP. More precisely, (a) contains two changes:
- Making
open(path, encoding="locale")use locale encoding in UTF-8 mode (Python 3.10 used UTF-8)- Add
locale.getencoding()that is same tolocale.getpreferredencoding(False)but returns locale encoding even in UTF-8 mode.These changes are important for (b). But they are not a big change needing PEP.
What should I do?
- Do not merge anything until PEP accepted.
- Merge (a) without waiting PEP accepted.
- Merge (a) and remove it from the PEP.
FWI, I and Victor are implementing
locale.getencoding()for now.https://bugs.python.org/issue47000 https://github.com/python/cpython/pull/32068
