Codeberg is a free/nonprofit hosted instance of Forgeo. Forgeo is a fork of Gitea created by Codeberg about a year ago when the governance of Gitea changed suddenly.
You can selfhost either Forgeo or Gitea.
There are other hosted instances of forgeo and gitea also available.
Gitlab is a hosted instance if gitlab.
You can also self host gitlab.
I assume there are other hosted instances of gitlab tho i cant think of any off the top of my head.
Kitty terminal has a lot of configurations for fonts. I beleive you can get down to adjustments for specific charecters. Idk if it uses the specific technology you are suggesting. But it is explained in the kitty.conf docs.
Actually you have to stay in more to get into this sort of thing.
Oh man fonts for coding are such a huge thing. There are people making their own forks of so they have certain glyphs, or a line through the zero (or vice versa) or little changes to other specific chars.
Uh well idk you personally so hard to say.
For me i like the remotely hosted ones.
Lots of other people run gitea locally.
