Edit: I now understand that for some reason my font does not have support for the glyphs in question, still don't know how to solve it.
I am using the "Lazy" package manager to configure neovim on my ubuntu machine, I have lualine and nvim-tree installed by Lazy, I have installed and am using a patched nerd font (hack regular) in the terminal.
For some reason both the symbols in the lualine status bar:
And in the nvim-tree panel all do not display properly:
I expected the nvim-tree symbols to be folders and files etc and the lualine symbols to be the language I am using etc. I tried figuring out if this is a font problem or a configuration problem but so far had no luck.
