The process code page from GetACP() is either an ANSI code page or CP_UTF8
(65001). It should never be a Western OEM code page such as 850. In that case,
a reliable unit test would check that the configured encoding is a particular
OEM code page. For example, spawn a new interpreter in a windowless console
session (i.e. creationflags=CREATE_NO_WINDOW). Set the session's input code
page to 850 via ctypes.WinDLL('kernel32').SetConsoleCP(850). Set
os.environ['PYTHONLEGACYWINDOWSSTDIO'] = '1'. Then spawn [sys.executable, '-c',
'import sys; print(sys.stdin.encoding)'], and verify that the output is 'cp850'.
