Of course these are "official part of a language". But why? Under whose authority? You could cite "actual usage", but many of the emoji in Unicode certainly have seen actual usage for 10+ years in East Asia, so they qualify. And many of the letters in Unicode were in fact designed by committee prior to mass adoption by an actual population (for example the Hangul alphabet), so a lot of scripts already in Unicode originally didn't meet that barrier.
* = Letters vs. characters: Elements of alphabets are referred to as letters. Alphabets are graphical representations of phonemes, but many other writing systems encode syllables (syllabaries, like the Japanese kana), morphemes or words (logographies) instead. Unicode contains examples of all of these, and thus not just letters. So we want to talk about characters instead.
That's pretty much my point.

You're just being petty or culturally arrogant at this point, TBH.
I say it again: If you want pictures and cliparts, use .png. If you want to write actual text, use fonts. It's as simple as that.
Why should my browser load thousands of pictures that are never used?!
Yes, it's ridiculous.
You're pulling numbers out of your ass. You also clearly don't know how font fallbacks work, despite having been told how they work in this very thread. Several times.
And you clearly don't understand that a) this thread contains unicode that my browser still doesn't show, despite your magic fallback and b) the fonts stil contain garbage that has nothing to do with fonts.
The nice part about having it Unicode is that if you copy and paste that character somewhere else, it'll still work. It never goes through what we used to have to deal where the same character value couldn't reliably be processed without knowing the intended encoding with certainty.
Fonts are not a clipart gallery and not a place for some committee to dump little pictures. If you want to show me a snowmen over the internet, use an image! Certainly people can understand an image of a snowmen.
