I disagree. The standard already has http://www.unicode.org/charts/PDF/U2400.pdf which is little different.

Sometimes I might want to show a dotted box for NBSP and sometimes a real NBSP. Or many other characters. Or show a RTL and LTR override character without actually overriding the text. You'd need a picture for that, because just putting in a glyph for it would also override the text.
