Hello,
I made a css font with your great icons : https://github.com/Silbad/iconoir-font/ if ok ?
The font you are proposing embeds all the icons, which degrades the site's performance. What's more, the style on some icons doesn't work. So.
Test with my demo when i load all icons :

I've tried to stay as close as possible to the original icons.
However, I've had a few problems with certain icons for various reasons (the eyes and musical notes of emojis, the dots on dice, snapchat, etc.).
In short, I'll be updating it alongside your releases ;)
