I'm not seeing any icons (on ios, tried a few browsers). Is the font (or svgs? Not at a computer to check how it's built) being served?
replies(3):
NerdFonts (and the right terminal emulator) were needed, and enough, there. Playing with AstroNvim, and blocked by use of yakuake.
Hoping that I can hot load something from https://www.nerdfonts.com/font-downloads, I'm not sure what from https://fonts.google.com/ has the needed ligatures or symbols.
