I think adding char8_t (and char16_t and char32_t) support to iostreams
is a separate concern from building something new. I suspect there is
sufficient demand for both. What we're really missing is a proposal for
something new. Well, we're also missing a proposal for how to add
support for char8_t (and char16_t and char32_t) to iostreams. I'm not
sure anyone wants std::u8cout, std::u16cout, and std::u32out. But
std::cout << u8"text" is problematic as well.

In San Diego, SG16 identified support for transcoding interfaces for
program boundaries as one of its highest priorities. So, ideas and
proposals are more than welcome.
