Look, I would love to be able to read/write Sanskrit, Arabic, Chinese, Japanese etc and share those content and have everyone render and see the same thing. The problem is that I feel like most of these are:
1. a kind of an open problem 2. very subjective 3. very, very subjective as what you is mostly dictated by the implementation (fonts)
For example, why does a gun emoji looks like water gun? Why is the skull-and-crossbones symbol looks so benign. In fact, it is often used as a meme (see deadass :skull:) Why is the basmala a single "character"?
In my opinion, people should just learn how to use kaomoji. Granted, kaomojis rely on a lot more than the Latin characters but it is at least artful, skillfull and a natural extension of the "actual" languages.

Yes, but it mostly happens naturally. I feel like what happens today mostly happens at the whim of a few passionate people in the standard.
