gollark: I've heard that Apple's Swift does it "properly", no idea about anything else.
gollark: I think most languages which don't have string handling explicitly designed for new Unicode thingies will have that sort of issue.
gollark: If JS was replaced with some other language but `script` tags and whatnot were still used, we would still have the exploits, probably.
gollark: It's mostly not really a JS problem.
gollark: I mean, the main reason JS is used in websites is just that you couldn't use anything else until... about three years ago with WASM, and that has a bunch of problems, more than its actual merits as a language, but I haven't heard much about it being particularly exploit-prone.
