Wow! Here’s a font editor in which each character is a list of lists of coordinates. Each list of N coordinates defines N-1 line(s): https://brutalita.com/
For example the right-pointing arrow glyph is the point of the arrow (2 lines) followed by the shaft:
{"→":[[[1,1],[2,2],[1,3]],[[0,2],[2,2]]], ...}
I’m thinking that to make a text scroller, on your Real Computer you could take only the used characters and put them in a list, and then the various strings you want to display are lists of indexes into that array.
I’m not sure I like it more than graph paper, but someone has already drawn an entire font so I’m going to make a renderer!
