Yes, there should be identifiers, and those are
already at least in 10646: such as U00010208 for the
mentioned etruscan letter. I was merely objecting
to the Unicode suggestion to use character
identifier identifcations for things that are not
characters, that is the unicode "surrogates".

I think it is OK to use the code points for thse, but not
short character IDs as that is really messing up
with the concepts of UCS (at least 10646).
Unicode should introduce a way to identify the
characters of planes outside BMP, which is consistent
with Amd 9.
