Thanks, I really do wonder why people lie to me or make things up. I guess that's what I get for never typing it into my IME in full.
> In my opinion while encoding pictures as text was a good idea at the time (due to limitations of mobile text messages), it makes no sense in 2017 where we have technology to easily inline any picture in the text even on mobile phones.
Even at the time, the character set was apparently meant to replace common phrases and text emoticons (for SMS, as you note). There's frankly no way anyone would have the time and energy to produce high quality custom images for simple messages, save for selfies.
Also, what about people whose skin is a shade in between those provided by the skin color emoji?
I mean, if you're not representing those people you're being racist, right?
Quite literally nobody has bright yellow skin. Emoji are not human beings, they are エモ → e-mo → emotion 字 → ji → characters (update: apparently I've been misled, but not in a way which changes my point, see reply below). The codepoints do not contain, have never contained, and will never contain a racial identity. They are an abstract representation of universal human emotions, just as generic as single-line ASCII emoticons.
Nobody's racial identity was represented by Unicode emoji faces to begin with, and certainly nobody any less than me.
