Because Unicode supposed to be a universal way for forming letters, not cater to stupid kids. Throw out that emoji shit out of Unicode!
I remembered something from years ago. Maybe 20 years or more. I sent a message to my friend, either through MSN or SMS, and the emojis I sent were different ones on the receiving end. Either it was the case for a different language settings or a different phone manufacturer or both.
Anyway, if we had unicode back then it would not have happened. Really a minor story though, I would not make importance of it.
It is still the case to some extent: the look of emojis is controlled by the font, not the Unicode per se. So the mountain pictogram in some font is a colorful image of the mountain, but on other font it is just a triangle.
