Oh yes, thank you for the link to that! Looks like that is an instruction set for representing the font glyphs themselves? I was talking about the instruction set in TFM which is for representing meta information, like ligatures and kerning between glyphs, and not for the actual glyphs. The glpyhs for the original TeX fonts are described using Metafont which is an interpreted language.
- atombender 2y agoGlyphs are generally defined as pure outlines (the "glyf" table [1]), and the instruction set is an optional system for things like grid fitting. Ligatures, kerning etc. are normal tables. [1] https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6glyf.html https://developer.apple.com/fonts/TrueType-Reference-Manual/...
