One thing to be aware of when using these fonts as I discovered on a large project today: this font won't work on windows phone 7 devices. Whilst these devices don't have much market share in the US it's quite a bit more in Europe (particularly the Nordic countries). The reason is that wp7 doesn't support font-face. The fix is to hide the opacity of the :before pseudo selector that sets the content of the dom element. Then you still reserve the space and then set the actual element to a background of the svg for the icon. It's a lot of work if you are using many icons but the alternative is unusable squares all over your application for WP7 users.
