Is there a similar library that can use local assets? I'd prefer to remove an external website dependency from my build process if possible.

I had that same question some time ago. I found that Google uses Python bindings[1] for fontforge, but it had that dependency on fontforge. So I opted for a Python-based solution called fonttools[2] instead, and it works pretty well. It comes with a utility called pyftsubset which you can use like so:

    pyftsubset FontAwesome.otf U+f0{2c,9e,99}

This creates a file called FontAwesome.otf.subset that has the selected glyphs. The FontAwesome site has the Unicode value on each icon page.
