I don't know if this is exactly the right proposal, but I think it's
probably appropriate to start gently pushing people towards UTF-8
rather than anything else. Unicode has largely won, AFAICT, and the
use cases for anything else are increasingly narrow. I don't think we
should try to be coercive, but there's a reasonable presumption that
people who haven't said what they want probably want UTF8.

I'm much less convinced about this idea. I think the number of people
who will be unhappy about the less-user-friendly sort order changes is
probably quite high. It's reasonable to want something more stable and
better version-controlled than libc, but switching to a simple
code-point sort seems like a high price to pay for that.
