My view: allowed, but not required.  But we should acknowledge that
state of affairs by allowing characters beyond Unicode in the source
character set.  (In particular, nobody should be forced to map
non-Unicode chars to the Unicode private use area.)

I strongly agreed that an implementations should never put things in the PUA (unless of course they were there before phase 1)
I again disagree that "characters beyond Unicode" is a thing compilers should care about
