Ok, but "\U+..." does not work today.

My example was unclear. I meant something like a one-char indexOf where the result would be used to slice that char.
That doesn't work today. That's the point.
But hey, if JS does not need to change then we can avoid trouble and keep on using 16-bit indexing and length. Is this really the best outcome?
