utf8 mode seems not working while loading site module with Python 3.11/3.12 in Windows

Bug report

Bug description:

I installed python 3.12.2 with rye 0.32.0, and it created a pth file that contains non-ascii file path.

$ cat .venv/Lib/site-packages/_tesuto.pth
C:\Users\XXXXXXXXX\Documents\tmp\テスト\src

Processing this file causes a UnicodeDecodeError and python prompt fails to open. (#87380)
I tried running python in utf-8 mode via $ python -X utf8 and PYTHONUTF8=1 environment variable, but not worked.
(not also with 3.11.8)

Error message is like following:

$ python -X utf8
Fatal Python error: init_import_site: Failed to import the site module
Python runtime state: initialized

tried but not worked

• installing python via pyenv

worked

• using python 3.10 or earlier
• changing the encoding of the pth file to cp932
