Setup Nerd Fonts in Chrome OS terminal

Press Ctr + Shift + j to open devtools console in crostini terminal.

Paste this to use Jetbrais Mono with ligatures:

term_.prefs_.set('font-family', 'JetBrains Mono Nerd Font, monospace');
term_.prefs_.set('user-css-text', '@font-face {font-family: "JetBrains Mono Nerd Font"; src: url("https://raw.githubusercontent.com/ryanoasis/nerd-fonts/master/patched-fonts/JetBrainsMono/Ligatures/Regular/JetBrainsMonoNerdFont-Regular.ttf"); font-weight: normal; font-style: normal;} x-row {text-rendering: optimizeLegibility;font-variant-ligatures: normal;}')

1. To change font, replace url path to raw .ttf file with your font in Nerd Fonts repository
2. To disable ligatures, delete x-row class in user-css-text parameter

There's no need to tinker with an arcane series of hacks or open the inspect tool. Use Fontconfig. The Debian image comes preinstalled with all the fc-* tools. Just put your font files into ~/.local/share/fonts/ and setup the font config you want, globally or just for your linux user.

Currently AFAIK you can't use any fonts customization natively without development mode. So buying chromebook you are in powerline fonts jail. And you can use fonts only in linux apps inside crostini container, as you mention.

There's very old and staled Issue 320364 about font installation. Hopefully(hah), someone will bring it to life.

Please update your original comment, you left a ")" at the end of .ttf in your url... That's why It doesn't work.

@vdegenne Update it... Thanks 👍

But just for information, I think this method is cleaner and will persist across the same account.
