Comment (by Troy Korjuslommi <troykor@…>):

 I tried your stream_char_common specialization solution.
 Didn't work. Probably some typo or other brain fart type thing.
 The template should define wchar_t as the type, but it somehow doesn't.
 requires_stringbuf gets set to false in lexical_cast_stream_traits, which
 it shouldn't if the type is char or wchar_t.

 I have to look at it again later. Maybe it'll come to me after a break.
 Anyway, if you feel like having a go at it, here's the one that fails (but
 matches).

        template < class Traits, class Alloc, template<class,class> class
 Iter >
        struct stream_char_common< boost::iterator_range< Iter <wchar_t*,
 std::basic_string<wchar_t,Traits,Alloc> > > >
        {
           typedef wchar_t type;
        };
