The font awesome font if downloaded locally allows you to render icons just by typing the icon names, any idea how it it does that?
For example, typing home changes the text to a home icon, if you have the font selected in your Figma or some of the other design tools.
I tried changing the unicode when I generated my icons using icomoon and fontello, but that didn't work.
Okay so if you use ligatures in icomoon, it works. I created a video about it too. (Not sure if posting the video is allowed, but can remove it if it isn't).
