I tried this on a bunch of different locale settings and concluded that
we need to restrict the locale to avoid failures: it falls over with
locale C. With that, it passes on all UTF8 LANG settings on RHEL8
and FreeBSD 12, and all except am_ET.UTF-8 on current macOS. I'm not
sure what the deal is with am_ET, but macOS has a long and sad history
of wonky UTF8 locales, so I was actually expecting worse. If the
buildfarm shows more problems, we can restrict it further --- I won't
be too upset if we end up restricting to just Linux systems, like
collate.linux.utf8. Anyway, pushed to see what happens.
