Hello all! I'm the brand and UI designer of a rather popular 3D animation program based on the game Minecraft, and as part of ongoing efforts to redesign the program and the associated websites, I'm working on building a new theme for its community forums. I designed an icon set for the program and I'd like to use it across the forums as well, instead of the default option of using FontAwesome. Thus, I'd like to know if there was any way to integrate a custom iconfont in a theme and use it instead of FA. Thanks in advance for your help!
