--- Comment #5 from ww898 <mikhail at pilin dot name> ---
The question about std::little_endian is still alive...

MSVC 2013/2015/2017, Clang 3.4/3.8 work on little endian computers x86/x86_64
and have little endian by default.
http://en.cppreference.com/w/cpp/locale/codecvt_mode says that "assume the
input is in little-endian byte order (applies to UTF-16 input only, the default
is big-endian)". May I wrong, but it says about input. My example produce the
UTF-16 output.

Could you please comment that?
