Sorry, I thought that was clear from my comments and from the context of
the discussion. For examples of some common .notdef glyphs as recommended
by Microsoft and Adobe, see
http://partners.adobe.com/asn/developer/opentype/recom.html. These
recommendations were drawn up specifically to discourage use of arbitrary
decorative forms, such as the spiral in Palatino Linotype, which are not
obviously indicating a problem in a document. Of course, establishing and
reinforcing a convention is necessary, and building on the existing
convention (box, box with something in it...) is better than trying to
invent a new convention.
