Unfortunately applying both Poly and Code gives you an imperfect result: the default l glyph has a flat base, Poly makes it narrower, and Code makes it a curly tail, but enable both (e.g. font-feature-settings: "ss01", "ss02") and you get the Poly glyph rather than the Code glyph or a hybrid, both of which would be nicer, and MB has said “won’t fix” (and I haven’t gone to the trouble of patching it myself). A demo of my own of Triplicate with use of both Poly and Code: https://chrismorgan.info/blog/rust-fizzbuzz/ https://chrismorgan.info/blog/rust-fizzbuzz/, code is all Poly + Code, compiler errors are just Code (it uses columnar alignment, so not Poly). The lowercase l can be seen in all the figures in one form or another (e.g. “else” in bold, “result” in regular, but not “println!” because italics always uses a curly-tailed l).
