Nice!

I made it more general:

   template<class InputIterator, typename OutputIterator>
   OutputIterator hex ( InputIterator first, InputIterator last, OutputIterator out )
   {
       for ( ; first != last; ++first )
           boost::spirit::karma::generate (out, boost::spirit::karma::hex, *first);
       return out;
   }

The problem with this is that if you pass it a sequence of wchar_t (say, from a wasting), it only encodes two hex digits per "character".
