Language icons from nvim-web-devicons not displaying

Screenshot illustrating issue with main configurations: https://pasteboard.co/oLWH4bIL2Pv8.png

I have DejaVuSansMono Nerd Font installed via AUR (nerd-fonts-complete), and indeed, vim-devicons in my tree panel seems to be displaying glyphs correctly. I am using i3wm and alacritty, with the patched font specified in the configurations (as you can see in the screenshot), and using the default layout for lualine.

However, next to the "lua" language indicator, there's an empty bubble, which indicates that nvim-web-devicons isn't displaying glyphs correctly. This is broken in nvim-qt as well, for the indicator icons for most languages (rust, python, vim, but not c/c++ or java for whatever reason).

What's boggling to me is that I have a laptop which also runs arch with almost identical configurations and packages, and everything is working properly on that machine. I can also SSH into my laptop where I know that those glyphs are working properly, run nvim-qt over SSH with X forwarding, and the glyphs are still broken on the forwarded window. I also have a workstation running Red Hat and MATE with this exact same nvim configuration, where the icons work properly.

Any ideas where the problem is originating?

UPDATE: Uninstalling vim-emoji-icon-theme fixed the problem. Apparently there was some problem with emoji fonts; I didn't have all the emojis that the plugin was trying to remap the icons to, or they weren't properly configured.
