FIGHT THE AIDS

Writing a greasemonkey script to block this unicode shit spam. Can I use regex with unicode? I have almost no experience with uni, any help would be appreciated.

OP here, did a little google work. Apparently the situation with unicode, regex amd JS suck. Should I take this route?

function containsNonLatinCodepoints(s) {
    return /[^\\u0000-\\u00ff]/.test(s);
  }
