How can I edit Font Awesome (or include my own icons)?

Question

Font Awesome is fully open source, so how can I tweak some icons as I wish, or add new icons? Let's say my primary vector tool is Inkscape (open source GPL).

The fontawesome package comes with files *.eot, *.otf, *.svg, *.ttf, and *.woff. The svg file does not successfully open in Inkscape. What program(s) can be used to edit these?

And once I edit the fonts, what guidelines should I follow? What unicode characters slots should I use? What should I be aware of when editing LESS source code to include new icons?

I'm not necessarily interested in submitting new icons to the official repo, I just want to fork and mutate it a bit, rather than having a couple of my own icons loaded ad-hoc.

Answer 1

You can use icomoon. Browse to the library page and use FontAwesome, you can augment FontAwesome's libary with your custom icons in SVG.

Answer 2

As well as the solution mentioned (which is perfect), you can also subset and combine icon fonts using:

• icnfnt (officially supported subsetting of font-awesome icons - original .com now a dead link, but the github repo is still available)
• fontello.com (create a custom subset from a number of icon fonts that are widely available)
