Neovide: Some icon fonts not displaying correctly like Font Awesome icons

[shivanju]

Hi. I am using neovide in Arch linux. The default font I use is FiraCode. I have noticed that neovide is not able to draw some icon characters properly which appear perfectly fine in my neovim setup in Alacritty terminal. I couldn't find any existing issues like this so creating a new one. Honestly, I don't even know whether this is a configuration issue or something else.
I have tried in all versions: Latest Pre-release, release and what's there in AUR
Here how it looks like now:

Here how it looks in Alacritty

Any help would be hugely appreciated.
Thanks,
Shivanju

Hi, @shivanju! What setting did you use to change the font for Neovide BTW?

[shivanju]

I used this in my vim config:

set guifont=Fira\ Code:h19

Thanks @shivanju, this setting worked for me.
I have the same problem as you now :) Some icons from my "JetBrainsMono Nerd Font" are not displayed correctly:

They should look like these:

I built neovide from repo today on Debian 10.

Same - built this morning on macOS 10.15

λ ~/C/r/neovide git rev-parse HEAD

Using Hack Nerd Font Mono - all icons display fine nvim in Kitty but only some do in Neovide

Hey! @shivanju @weiss-d I'm using Arch and the Nerd Fonts, I changed the settings to:

set guifont=FiraCode\ Nerd\ Font:h19

and it worked for me. @ccakes I have not tried on macOS, but I believe it should work.

I think this may be a font fallback thing. If you font got set properly, it should get the extra icons in that exact font correct. However if those icons aren't a part of the font, it probably won't work due to font fallback handling.

this issue goes into detail about what the plan is for fixing this. But its a ways out yet.

I think this has been fixed in main. Please reopen if you come back to this and the issue remains.

EDIT: It turns out the fonts are there, just cut in half. The window being displayed is from https://github.com/folke/which-key.nvim. Any ideas on where to start looking for this?

I'm still having this issue unfortunately.
