Yes, it's definitely going to be indexing. If strings were represented
internally in UTF-8, each of those calls would need to scan from the
beginning of the string, counting and discarding characters until it
finds the place to start, then counting and retaining characters until
it finds the place to stop. Definite example of what I'm looking for,
thanks!
