Not really. boost/program_options/detail/utf8_codecvt_facet.hpp only
includes boost/detail/utf8_codecvt_facet.hpp, with some setup.

The only documentation in the comment in boost/detail/utf8_codecvt_facet.hpp

Those are *different* .hpp files -- each forwarding the the one in boost/detail.

If you're on windows, wchar_t is only 16-bit anyway. If you are on a different
operating system, I don't know any code in Boost that will convert UTF-16
into a sequence of 32-bit wchar_t. However, the internet has a pile of such
converters and this topic was discussed on this mailing list, too.
