#### 🎯 Subject of the issue

Experienced behavior:
this morning I updated some deps on my computers and some fonts were updated as well but this is not a big deal since this has happened before, but after the update finished I noticed some icons on my neovim were wrong like the `Gemfile` icon and the `X` for closing a buffer:

This was weird so I decided to delete all custom fonts I had, clean up the cache, re-download them manually, and reinstall it. To my surprise, nothing has changed

No idea what is going on, this is my text configuration on iTerm2:

Neovim version:

```
:version
NVIM v0.9.0
Build type: Release
LuaJIT 2.1.0-beta3

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/opt/homebrew/Cellar/neovim/0.9.0/share/nvim"
```

No Neovim config has been changed prior to today or after this.

Expected behavior:
X and missing icons should exist

Example symbols:

I guess it should've been the "unknown file" icon
