--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Argh, this only works if the wide encoding happens to be UCS-4 (or for 16-bit
wchar_t, UCS-2) because std::codecvt_utf8 only supports converting between that
and UTF-8. Which is why I used std::codecvt<wchar_t, char, mbstate_t> in the
first place.
