For may programs, particularly with reference to Font settings, if you
select text containing a multitude of font formats it will show a
minus sign '-' as it can't show multiple values.  If it were me:

2 = tick in the Box
3 = x in the Box
4 = - in the Box.

It might not be quite standard but I think most people would figure it
out pretty quickly.
