If you use custom font. icons in LunarVim could look broken. Use this command to display what UTF codes uses Lunarvim for icons. After taht use it in https://sw.kovidgoyal.net/kitty/conf/#opt-kitty.symbol_map to map that UTF codes ranges to some Nerd Font. So, you do not need to patch our font and use its ligatures as well
First - open icons file in Lunarvim folder
lvim ~/.local/share/lunarvim/lvim/lua/lvim/icons.luaThen activate command mode and apply this command
