* "Smiley" isn't "proprietary", it's a generic name like "emoticon". -) has long been referred to as a "smiley". The overlap in use between "smiley"/"emoticon" and "emoji" is new. I'd say it's an incorrect use, but as language changes, I wouldn't be surprised if this becomes a widely accepted (and therefore correct) usage of the word (much to my chagrin ;). Note that even Apple's doing this now: they described their animated 3D Apple Watch emoticons as "emoji". —
