Nerd fonts removed support for some of the icons, and replaced with other codes, and even using ttf-material-design-icons-extended on Arch does not work. Nerd font offers replacement for all of the icons, as far as i can tell, so maybe themes should be updated to use new icons from Nerd fonts? Replacing with new values from nerdfonts works. For example f5aa (blender) can be replaced with f00ab? Not sure if this is something you would care too do in this repo, or should original creators make the changes. Here is changelog on nerdfonts https://www.nerdfonts.com/releases.
I tried out the theme which utilises the material design icons and I'm using the package ttf-material-design-icons-extended alongside a nerdfont, is this problem happening for you right now?
