Siri can Read Emojis! (Video)
Check this video out.
My favorite is the "Smiling Pile of Poo."
I discovered it the other day when I had Siri read a message with a Santa Clause emoji at the end and she said "Santa Clause." Many may be aware of this already, but many probably aren't.
It can be useful if you wanna know what one of the symbols means.
