The homepage is somewhat misleading, you can use it without Nerd Fonts and there's actually a preset config listed for it mentioned on the Presets page [0] with the note:

> This preset will become the default preset in a future release of starship

It also links to an open issue on the GH repo about it [1] (although that issue is 2 years old and doesn't seem to be top priority.)

Many code fonts have the bat majority of the symbols already. The new MS Terminal for Windows uses Cascadia, and IIRC only missing the node logo IIRC.

Other fonts work to. I use Fira Code myself.

It works fine out of the box on mac and windows, have not tried it on linux yet (only over ssh).
