@adm304 Make sure you are using the console inside the terminal app itself. You can also find it here chrome-untrusted://terminal/html/terminal.html. If you're using the latest version of ChromeOS, unfortunately this won't work as you can't open the js console inside the terminal for now.

Is there still a way to use Nerd fonts in the new version of Chrome OS?

I've made some progress on this. First you can open the inspector by going to chrome://inspect/#other then use C-f to search for terminal.html. There will be 2 of them. You want the one with ?command. Click "inspect" and you'll be in the inspector. The next issue will be CORS.
I temporarily got around that by copying the .ttf into a directory being served on localhost.

It Worked!

I've got it working on my Chromebook with an arcane series of hacks. Try it and let me know if it works for you.

I switched to Kitty terminal. Much better all round.

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.

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