Why bother to encode them as distinct characters? "For purposes of
documentation" isn't a good reason to encode these things, which are simply
a set of fall-back glyphs for user convenience to show what isn't
installed! If you want documentation for the Last Resort font, just make
documentation (or ask Apple to make some).
