Will do. Words can be a lot more specific, like the periodic table is elements, which make up 4 KRV Utensils.
Emoji have their place, but often have associative meanings only known to the viewer. So, sharing the meaning with a 3rd party requires additional translation, which can have prerequisites to understanding that take time.
I imagine with space targets anyway, the Emoji Utensil will be selected if there are advanced lifeforms, or archaeological remains. Should be much more direct, and less story telling in this application, based on what I've seen so far.
