Knowing that everything in here is people asking why their font is missing: I highly recommend having a look at
[ MAPLE MONO ]
(on Github https://github.com/subframe7536/Maple-font). It has amazing readability, looks nice, is compatible with NF if you use that. I received compliments from people looking over my shoulder for my f'ing font?! Huge shoutout to subframe7536 ^^
While we're dropping lesser-known coding fonts, here's my favorite, Lotion [0]. It's cute and playful but also very legible and clean.
Italics turn into cursive... I cannot imagine ever wanting this in my IDE, but that's just me.
Seconding Maple Mono - it's very nice.
I've been a long time Fira Code user, but recently switched to Maple - I love it. Mostly because of the "single storey" `a`, but that's just a personal preference of mine.
