I'd like to use Google's material icons https://design.google.com/icons/ as a font, but am worried about browser support. Is there a guide for what CSS, fallbacks, etc. to use? Do I need to do browser sniffing? What are the known limitations?
<link href="https://fonts.googleapis.com/icon?family=Material+Icons"
rel="stylesheet">
<i class="material-icons edit_icon">more_vert</i>
For ie9 and below, they say to use the below snippet, but it's blank in my IE 11's emulator for IE 9. Does it work in the actual IE9?
<i class="material-icons"></i>
Would I need to do browser sniffing or do I just include both and browsers know to only show one?
This page lists issues with mobile https://github.com/google/material-design-icons/issues/179 as does this Why Google Material Icons Can't be Shown on Mobile. They offer different solutions.
Is there a well-tested definitive guide? Is the world just not ready for these icons to be used as a font?
