> Why is it being specified that the current LC_CTYPE encoding should be ignored in Windows when a "locale" encoding is requested?
Because `encoding="locale"` must be replacement of the current `encoding=None` (i.e. locale.getpreferredencoding(False).
`encoding=None` behavior will be changed if we change the default encoding or enable UTF-8 mode by default. So we are adding an explicit name to current behavior.
So It is not an option to assign other encoding. See PEP 597 for detail.
I know you are proposing to use CRT locale on Windows. If we change the `locale.getpreferredencoding(False)` to use CRT locale, `encoding="locale"` follow it.
But please discuss it in another issue.
