In hierarchies where the language used can have characters of various
widths, it is up to the hierarchy admins to apply some sensible rule. Any
'default' rule we put in USEFOR will be for the normal case of fixed width
characters.
However (when I18N has happened) a fixed-width character might still be
made up of a base character and (say) an underlining, or some funny thing
on top, or whatever. According to Martin, that character would still
contain two or more "glyphs" (as Unicode uses the term). Therefore, it is
the wrong term for our purpose.
