For those curious about icon fonts versus SVG, though icon fonts can be easier for the developer to use, there are drawbacks for your users (especially in accessibility).

But don’t take my word for it: https://css-tricks.com/icon-fonts-vs-svg/

“It all comes down to browser support. If you can go IE 9+ / Android 3+, inline SVG is better at pretty much everything than icon fonts. If you need the deeper browser support, I feel like an inline SVG fallback would be too big of a pain to be worth it (maintaining a PNG copy, inserting an additional element to display PNG version, hiding SVG element… it’s weighty).”
