Font chooser has checkbox limiting choosable fonts to those which can display all characters in example.

There should be a way to only display fonts which can render the example string in the font choose dialog. Also I've always meant to substitute fonts when there are missing characters.

Connor was trying to find a font with the perpendicular symbol, and this would have been useful. See https://sourceforge.net/p/autoplot/bugs/2738/.
