vim-devicons not rendered properly

Question

I am configuring vim-devicons for my neovim and this is my init.nvim:

:set number
:set autoindent
:set tabstop=4
:set shiftwidth=4
:set smarttab
:set softtabstop=4
:set mouse=a

call plug#begin()
Plug 'https://github.com/preservim/nerdtree' " NerdTree
Plug 'https://github.com/rafi/awesome-vim-colorschemes' " Retro Scheme
Plug 'https://github.com/ryanoasis/vim-devicons' " Developer Icons
call plug#end()

set encoding=UTF-8

:colorscheme molokayo

"let g:NERDTreeDirArrowExpandable="+"
"let g:NERDTreeDirArrowCollapsible="~"

but devicons are not rendered on my terminal at all (for hyper, gnome-terminal, terminator):

The font I use here is Fira Code but it doesn't work for Cascadia either.

I have also tried the FAQ routine from vim-devicons:

1. :echo loaded_webdevicons returns 1
2. :echo g:webdevicons_enable returns 1
3. :echo g:webdevicons_enable_nerdtree returns 1
4. :echo g:WebDevIconsUnicodeDecorateFileNodesDefaultSymbol gives me an wrongly rendered symbol.

Now how do I fix it the get devicons working?

Answer 1

You have to:

• Download and install the corresponding font from: patched-fonts for your platform
• Tell Neovim to use installed nerd font (e.g.: :set guifont=FiraCode\ Nerd\ Font\ Mono:h9:cANSI)
• Install and use the devicons plugin (Plug 'ryanoasis/vim-devicons' with vim-plug)
