Thanks.

Yes, we should design the display of these special characters as a
single coherent feature.  For example, I discovered a few days ago
that we don't display the U+2028 LINE SEPARATOR character as a line
separator.  And there are many other similar Unicode characters that
need our consideration.

(I started to elaborate about this, but found out that I already said
that in http://lists.gnu.org/archive/html/emacs-devel/2008-04/msg01504.html).

Agreed.  How about a bug report on this, to avoid forgetting the
issue?

I agree.
