Need Help badly Something like GetUnitIcon()

Is there a way to get an unit type icon?

If there isn't is there a function to get the raw code of a unit (A2Te) , cause I think I can do something like < + rawcode + ,Art> to get the icon.

I believe uico is the code for the Interface icon. So for example, the code for a footman would be:
<hfoo, uico>
I don't know if this can be accessed through triggers though emote_confused
