Author here, yes you're correct. The name is a bit of misnomer, and to do it truly with ASCII I'd have to move data back to the CPU which had pretty bad performance. I took a bit of artistic liberty and decided to draw my own ASCII-esque glyphs using signed distance functions. I'm considering adding a setting to swap the modes so that it does use true ASCII but again it'd be pretty rough performance on large screens.
