Edit: I'm on macOS 15 if that helps.
For instance, I want to replace the nf-md-numeric_1_circle_outline icon (you can search that in https://www.nerdfonts.com/cheat-sheet to see), with this Apple SF Symbol1.circle instead. I use a nerd font in Neovide (an Nvim GUI), where I can paste in the text character for 1.circle and it shows correctly without additional steps. On nerdfonts.com, it says at the bottom "You can even specify a custom symbol font with the --custom option to include even more glyphs." but I didn't find any instructions for how exactly to make a font file with the glyphs I want. I want to be able to overwrite any nerd icon with one in the SF Symbols app.
