This does not work for entries like await "😀😀😀";"😀".
edit: I think I finally succeeded.

While getting it exactly right is, of course, preferred, it's totally OK to land something that is an improvement that still leaves some edge cases unsolved. await "😀😀😀";"😀" doesn't work currently, so it's OK if your fix doesn't fix that.

Ok, thanks! Finally I succeeded, and I don't know why I was looking for a complex solution. Just break the surrogates, so the array has the same length as the string and the surrogates will normally not be broken at the end (unless there is a bug with some indexes or acorn, but I doubt it)
