Yep, "LC_CTYPE=en_US.UTF-8" is what the current version of PEP 538 has
as a fallback if neither C.UTF-8 nor C.utf8 is available.

However, that's also the part of PEP 538 that I think can just be
dropped entirely and replaced with PEP 540's "assume UTF-8" behaviour
instead.

I was already considering that as an option when I last updated the
PEP (see https://www.python.org/dev/peps/pep-0538/#relationship-with-other-peps
), and now that Victor actually has a working reference implementation
for the PEP 540 approach, I think it's the right way to go.

Cheers,
Nick.
