[New-bugs-announce] [issue30672] PEP 538: Unexpected locale behaviour on Mac OS X

[Nick Coghlan]

New submission from Nick Coghlan:

To get the new PEP 538 tests passing on Mac OS X (see [1,2]), I ended up having to skip the following test scenarios:

    LANG=UTF-8 (behaves like LANG=C, *not* LC_CTYPE=UTF-8)
    LANG=POSIX (behaves like a distinct locale is set, not LANG=C)
    LC_CTYPE=POSIX (behaves like a distinct locale is set, not LANG=C)
    LC_ALL=POSIX (behaves like a distinct locale is set, not LANG=C)

However, I'm not sure whether that should be diagnosed as a pure testing problem, where we change the test's expectations to match the current behaviour, or a bug in the PEP 538 implementation, where we should be updating it to produce the behaviour that the tests were originally expecting.
