UnicodeEncodeError: 'utf-8' codec can't encode character '\udcff' in position 27: surrogates not allowed

On Python 3.11 when creating a directory containing \udcff I receive the following error that happens even when I'm not running the inspect module.

sam@samtop /tmp/bpo/python\M-^?-3.11 (git)-[main] % ./python
Exception ignored error evaluating path:

./python -m inspect can maybe reconfigure sys.stdout to use a different error handler than strict? Like backslashreplace or replace. I don't think that it's worth it to add special code just to display "Origin: ", many other strings can contain characters not encoding to stdout encoding (UTF-8 in your case).

Does it work to just add: sys.stdout.reconfigure(errors="backslashreplace")?
