New submission from Inada Naoki <songofaca...@gmail.com>:

Currently, `encoding="locale"` is just shortcut of 
`encoding=locale.getpreferredencoding(False)`.

`encoding="locale"` means that "locale encoding should be used here, even if 
Python default encoding is changed to UTF-8".

I am not sure that UTF-8 mode becomes the default or not.
But some user want to use UTF-8 mode to change default encoding in their Python 
environments without waiting Python default encoding changed.

So I think `encoding="locale"` should use real locale encoding (ACP on Windows) 
regardless UTF-8 mode is enabled or not.

Currently, UTF-8 mode affects to `_Py_GetLocaleEncoding()`. So it is difficult 
that make encoding="locale" ignores UTF-8 mode.
Is it safe to use `locale.getlocale(locale.LC_CTYPE)[1] or "UTF-8"`?
