That's not a problem.  As you say, "presumably you're doing that for
good reason."

The problem is that someone will use code written by someone using a
future version and run it with a past version, and the assert will
trigger.  I don't see any good reason why it should.  The Unicode
Standard explicitly specifies how unknown code points should be
handled.  Raising an exception is not part of that spec.
