But this just makes the example convince me that code_unit_sequence is
even less useful. If I understood correctly you wanted to show that
supporting utf32be in code_point_sequence makes things more complicated
for the user. Correct me if my understanding of the interface is wrong,
but, roughly, I don't think I can be convinced that:

code_unit_sequence<utf16, big_endian> cus(std::move(source));
code_point_sequence<utf16> cps(std::move(cus));

... is simpler than:

code_point_sequence<utf16be> cps(std::move(source));

As far as I can tell the only use for a code_unit_sequence is to pass it
to the constructor of a code_point_sequence.
