bug#44236: [PATCH] xdisp: Apply nobreak-char-display also to NARROW NO-BREAK SPACE U+202F

(Not speaking to how annoying anything might be, here.)

`nobreak-char-display' is what it is.  It can't be
expected to do more than it does, IMO.  Its aim is
to highlight non-ASCII chars that look similar to
ASCII space and hyphen.

That's already too much, IMO.  I've said before that
it's a weakness that users can't separate those two
(highlighting look-alikes for SPC and hyphen).  They
shouldn't be hard-coupled together (IMO).

And I mentioned my library `highlight-chars.el',
which lets you highlight different sets of chars.
And code can control that.  It sounds like that's
maybe what's being looked for here: highlight certain
chars in certain contexts (not just everywhere).
