Strange glyph icons appear. #700

Describe the bug

Following the guide of cloning the repository and opening up neovim, the setup completes, but I see strange glyphs everywhere instead of the intended icons.

To Reproduce

I assume this has to do with the fonts on a system, so not sure how to reproduce.

• OS: Ubuntu:20.04 LTS
• Terminal: zsh
