[issue45176] Many regtest failures on Windows with non-ASCII account name

In Windows, the standard I/O encoding of the spawn_python() child defaults to the process active code page, i.e. GetACP(). In Windows 10, the active code page can be set to UTF-8 at the system or application level, but most systems and applications still use a legacy code page. Python's default can be overridden to UTF-8 for standard I/O via PYTHONIOENCODING, or for all I/O via PYTHONUTF8 or "-X utf8=1". I would recommend using one of these UTF-8 options instead of trying to make a test work with the legacy code page. There is no guarantee, and should be no guarantee, that a filesystem path, which is Unicode, can be encoded using a legacy code page.
