[New-bugs-announce] [issue31565] open() doesn't use locale.getpreferredencoding()

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

It is documented that the default encoding for open() and io.TextIOWrapper() is locale.getpreferredencoding(). But actually the C implementation in Python 3 uses _bootlocale.getpreferredencoding(). Monkey-patching locale.getpreferredencoding doesn't affect open().
