Developer in Actionscript AIR / Starling / Feathers

To develop is a List (default Feathers Theme) with ItemRenderers of different sizes (top-Left aligned) displaying a label text with emojis. Preferably the emojis should be the device emoji font. (iOS or Android) If a font must be used which is NOT in the device, then this font should display/use iOS-looking emojis. For reference look at the image with the example.
