Well, by definition the do-not-litter sign could be considered a
no-dreck character ;-)
More seriously, there are many symbols for which widespread use makes a
character based solution appealing - so that you get the benefit of
document portability, searchability, ability to do other semantic
processing etc. that comes with encoding semantics on the character
level as opposed to relying on the insertion of pictures.
There's also the issue of the fact that our existing repertoire is very
one-sided towards US and in some cases Asian practice, because of the
sources that were used for Unicode 1.0. In particular, European usage of
common symbols is poorly supported. But there are also some common
symbols used in Asia that are not supported because they did not occur
in legacy sets (for example the little sound-recording symbol that looks
like a black rectangle with a white double loop inscribed).
As a result, I'm happy to see that some people are working on proposals
to address this, so that as a result, the limits that Unicode draws on
supporting symbols as characters leave room for a more consistent set.
As with all proposals, it will be necessary to review and fine tune them.
There's a problem specific to single character proposals because the
nature of the proposal is all-or-nothing, rather than allowing
subsetting or assigning different levels of priority. Because of this,
UTC decisions on such proposals rarely result in useful precedents.
