Wrong font icons on some devices

Created by: Tomas-M

The glyph font icons are somehow broken on some devices. For example on my android phone (android 2.1) some of the icons are broken, but others look OK. See attached screenshot.

I'm not sure what is cause of that, yet if it is possible to show some of the icons properly on my device, it should be possible to fix it to show all of them properly. If you need more information, let me know. Thank you.
