Unicode definitely has flaws but that doesn't mean we should throw the baby out with the bathwater and go back to "ASCII and other character sets." There's a reason we moved on from that world. However, I bet we will see another encoding coming up eventually (within 30 years) which solves the problems Unicode currently has and introduces a new set of problems as well. I saw this comment [0] about how that encoding should get started.

> Greek, for example, has a lot of special-casing in Unicode. Korean is devilishly hard to render correctly the way Unicode handles it. And once you get into the right-to-left scripts, scripts that sort-of-sometimes omit vowels, or Devanagari (the script used to write a bunch of widely-spoken languages in India), you start needing very different capabilities than what's involved in Western European writing. _The better approach probably would have been to start with those, and work back to the European scripts_

Funnily enough, URLs still can't do actual Unicode.
