It's this code, I guess, from 2016, so it's not recent:

  NSLocale *locale = [NSLocale currentLocale];

  NSTRACE ("ns_init_locale");

  @try
    {
      /* It seems macOS should probably use UTF-8 everywhere.
         'localeIdentifier' does not specify the encoding, and I can't
         find any way to get the OS to tell us which encoding to use,
         so hard-code '.UTF-8'.  */
      NSString *localeID = [NSString stringWithFormat:@"%@.UTF-8",
                                     [locale localeIdentifier]];

      /* Set LANG to locale, but not if LANG is already set.  */
      setenv("LANG", [localeID UTF8String], 0);
    }

And...  it's a Macos bug?  Googling a bit seems to say that this does
indeed return invalid locale identifiers -- just language glued together
with the country, resulting in identifiers that doesn't match any
locales the OS knows about.

So...  I don't know what to do about that.  Is there a way to check that
the identifier is valid?
