This is where the (Boost.)Locale and (Boost.)Unicode libraries could provide
insight into how to extend the std::string interface or be the testbed for
new additions to the standard library related to string manipulation.
(Provided, the standard adopts UTF-8 as a native encoding. Or does it already ?)
