I think a better solution would have been to only have glyph in Unicode, and then any emoticons would have been implemented by sending embedded images in various chat protocols. Its much easier for a receiver to parse a common image format then to make a font that includes all emoticons. It would also allow users to add their own emoticons, and you wouldn't have any ambiguity of what you are sending. Some facial expression could be argued dont express quite the same thing in all fonts, so there may be something lost in translation between users of different platforms. I found a paper on it! https://brenthecht.com/publications/cscw2018_emojiimpact.pdf https://brenthecht.com/publications/cscw2018_emojiimpact.pdf
