INADA Naoki added the comment: If this warnings are disabled by default, who enable it? How about just remove them? I'm OK to remove them all. Since it's not ideal, nothing go worse than Python 3.6. Additionally, if PEP 540 is accepted, we can use UTF-8 for stdio and filesystem encoding even

[issue30690] ChainMap doesn't preserve the order of ordered mappings

[issue30672] PEP 538: Unexpected locale behaviour on Mac OS X

Nick Coghlan added the comment: For the case where POSIX is a distinct locale from the default C locale (rather than a simple alias), I'm leaning towards taking PEP 538 literally, and adjusting the affected test cases to assume that locale coercion *won't* happen for that case on Mac OS X. I

[issue30565] PEP 538: silence locale coercion and compatibility warnings by default?

Nick Coghlan added the comment: By having the warnings always compiled in, but off by default, "PYTHONCOERCECLOCALE=warn" becomes a debugging tool for integration failures that we (or end users) suspect might be due to the locale coercion behaviour. It's essentially an even more esoteric
