I don't think this is right. My guess is that in most cases where it matters either way, the intention is to get a count that's consistent with .charAt(), .indexOf(), .slice(), RegExp match.index, and every other place where string indexes are used. That said, of course this is a sensible feature to add; but calling it ".realLength" wouldn't help anyone understand the rather fine distinction at issue. -j
