IconicsTextView not working on some devices
On some devices the IconicsTextView do not display the icons at all or display dummy unicode characters. IconicsImageView works fine, though. The problem popped up while testing in Google Cloud Test Lab. Here some examples:

**This is a working example, testen on Nexus 4 - Android 5.1 | Deutsch**

I tried it with Community Material Typeface and with my own custom font.
