Why not boost::string (explicitly stating in the docs that it is UTF-8-based) ?
the name u8string suggests to me that it is meant for some special case
of character encoding and the (encoding agnostic/native) std::string
is still the way
to go.

IMO we should send the message that UTF-8 is
and the other encodings like the native_t (or even ansi_t,
ibm_cp_xyz_t, string16_t,
string32_t, ...) are the special cases and they should be treated as such.
