Font Awesome has a cheatsheet where they've converted their icons into html entities that you can copy and paste right into Sketch (and other editing programs), that changes the type element to the icon you want (as long as you have the font installed). Demo: http://recordit.co/Irr9HBpVPX
I'm wondering how to do this with my company's own custom font. We have an internal living style guide that has all of our custom icons as CSS content code (as pseudo element background images), but not as type. I'm wondering how to convert them to type-able content that I could just copy and paste in using our custom font in Sketch.
Any help appreciated – thanks
