My intent was to make it play nice with postMessage:

foo.postMessage("hi there", location.origin);


window.addEventListener("message", function(e) {
  if (e.origin != location.origin)
    return; // Some other origin is trying to confuse us!
}, false);

Does postMessage use the Unicode serialization or the ASCII serialization?
