@dancingtreefrog Yep. All the Latin-based writing systems got stuck together, but that was before Unicode; it inherited that particular mess.
But it didn't inherit the CJK Han Unification mess. There was a Japanese encoding that had that solved BEFORE Unicode existed. And the ISO explicitly binned a solution that Japan came up with, with Korean (and presumably Chinese but I don't know) support and forced Han Unification without consensus of the three nations involved.
Because of course.
