Some icons not show correctly

When using nvim-tree, some icons display only a rectangle, like the one in the image for prettier. The git status icons of nvim-tree also show a rectangle.
I tried many Nerd fonts but nothing changed.

OS: Arch Linux
Neovim: v0.9.5
Terminal: Kitty
Shell: fish
nvim-web-devicons: { "branch": "master", "commit": "cb0c967c9723a76ccb1be0cc3a9a10e577d2f6ec" }
Current Font: FiraCode Nerd Font

What are the other icons that don't display properly? I think Prettier icons were added recently and perhaps your font is not of latest upstream version.

Updated I checked again and the git status icons of nvim-tree.lua is good now. Prettierrc is still a rectangle.
I tried downloading and installing FireCode Nerd again but it doesn't work. How can I check which font is updated your icons?
