Apparently I'm trying to make life difficult for myself. My first attempt was with a Font Awesome font and it failed, so I assumed (badly) based on the font selection available to the input control that AIM was using the Kendo library of fonts for the banner (4 such Kendo fonts are available). It turns out that not all Font Awesome fonts on the cheatsheet are in the folder. So I've been chasing my tail the whole time.
