How do assistive technologies handle icon fonts?

Jemma and I are doing some accessibility testing on icon fonts—especially Font Awesome—and how assistive technologies handle them. I’ve setup a GitHub repository called Font Awesome <https://github.com/MichielBijl/font-awesome> (because we initially targeted that specific library; should rename it). I’ve already added one test example and some test results, but suggestions for more examples (ways to fix the issue of icon fonts being announced weird), or test results for existing tests, or even tips on how to display test results properly; it’s all welcome!
