If we want to make this more general-purpose, we should time the code with very long strings. It could be that beyond some length the UTF-8 verification, if it fails, will make the conversion slower, in which case we probably should not take the shortcut beyond that length limit. Or we might document that non-UTF-8 strings will be slower to convert, if that's acceptable.
