Earlier quoted context omitted.
For as inclusive as that mission is, it seems weird to me how limited in certain areas unicode is. For instance, people use peach emoji since there isn't one for butt, eggplant since there's no penis, etc. This doesn't contradict the stated goal exactly, but it seems against the spirit of it at least.
One could argue that emoji should have never been added to Unicode in the first place. Peaches and butts are images, pictures, illustrations, whatever - but they are not characters. There's no writing system which has a colored drawing of a peach as a character.
So a peach emoji is not the same thing as the iOS peach-emoji-image. Similar to how changing my font doesn't change the actual characters.
I don't think including emojis was a great idea, but now that it's happened and people everywhere use them, emoji have become characters. I agree with your point, but it's already happened and so now there's not really any going back.
