Consider reading unicode arrow or line characters

[samliddicott]

Have you considered limited support for reading and interpreting unicode characters?

U+00B7 middle dot could be used for dotted lines, instead of hyphen

Or, using math symbols: http://jrgraphix.net/r/Unicode/2200-22FF
U+22EE ⋮ vertical 3 dots
U+22EF ⋯ horizontal 3 dots
U+22F0 ⋰ dotted slash
U+22F1 ⋱ dotted backslash

Box drawing lines: http://jrgraphix.net/r/Unicode/2500-257F
(includes rounded conrners, diagonal crossover etc).

Unicode arrows: http://jrgraphix.net/r/Unicode/2190-21FF
Supplementary arrows A: http://jrgraphix.net/r/Unicode/27F0-27FF
Supplementary arrows B: http://jrgraphix.net/r/Unicode/2900-297F
(oh my eyes)

I realise that there could be no end to this, and "almost" with so many symbols and a fixed-width font, who needs SVG... (Me, me, I need SVG).
