Hi,

Nick Coghlan pushed his implementation of his PEP 538: nice! Nice step forward to UTF-8 everywhere ;-) I would prefer to not be annoyed by warning messages about encodings at startup if possible: "Python detected LCCTYPE=C: LCCTYPE coerced to C.UTF-8 (set another locale or PYTHONCOERCECLOCALE=0 to disable this locale coercion behavior)."

This is intentional behavior, to motivate people to use UTF-8 locale without coercion.

Note: I don't consider that 2>/dev/null is a good practice to ignore a single warning, since it will ignore all message written into stderr, including useful warnings like ResourceWarning or "Exception ignored ...".

I think "Good practice" is set LC_CTYPE=C.UTF-8 environment variable, as warning says.

When PEP 540 is accepted, it can be used to disable the warning too.

Regards,
