I replied to your ticket, but I'll copy the answer here, if someone else stumbles upon this Android 4.2 bug:
This seems like a bug in Adnroid 4.2 - similar issue is reported
in the Android bug tracker - that some Unicode ranges doesn't get rendered in Android 4.2 WebView, while they worked fine in 4.1. The issue can be easily reproduced without Kendo UI Mobile:
src: url("fonts/-hats.woff") format("woff"),
font: 5em/1em Hats;
The only workaround I can think of is that you should use the same Unicode range that we used for our font - starting from \E000.
