Look at the Silk icon set and pick some.  It's pretty good.  I'll do the
rest :)

The problem is that if you don't have UTF-8 enabled it's broken (and
there are many other console encodings, so we need general Unicode
capability *and* font support for those characters).  So for now it has
to be customized by the user.  Is there a way in GNU Emacs and XEmacs to
find out if it's safe to output a specific Unicode character on the
console?  I would assume not, since you can switch the terminal encoding
and the font at any time in gnome-terminal at least.

Maybe we could add a :unicode-char property and let the user enable
Unicode output as a global option.  I don't think it's worthwhile but if
people want it I'll add it.

Specifically for the Important mark, why use the ENVELOPE character?
For general consumption would use something like the *EXCLAMATION*
characters (FULLWIDTH EXCLAMATION MARK maybe), but essentially it's a
matter of taste.  As I showed in my setup, I use Greek letters because I
think they look nice in that context, but most people probably won't.

The Silk icon set, OTOH, is pretty popular on the web so using it makes
sense, and it already has some of the image lexicon we're looking for.

Thanks
