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 ^^
They have not posted anything on social media in a long time and there was some downtime a few months ago. I would really like to use this primarily, but it is really a problem when your DNS suddenly becomes unavailable without any note from the devs ^^
