Indeed, one pain point of unicode is CJK unification. https://heistak.github.io/your-code-displays-japanese-wrong/

the fact that there is seemingly no interest in fixing this, and if you want chinese and japanese in the same document, you're just fucked, forever, is crazy to me.

They should add separate code points for each variant and at least make it possible to avoid the problem in new documents. I've heard the arguments against this before, but the longer you wait, the worse the problem gets.
