As I've mentioned before, stringstreams *never* perform code conversion. Of the
standard streams, *only* file streams use codecvts.

If you want something that behaves like a stringstream but performs code
conversion, you can use

    #include <boost/iostreams/code_converter.hpp>
    #include <boost/iostreams/stream.hpp>
    #include <libs/iostreams/example/container_device.hpp>

    namespace io = boost::iostreams;
    namespace ex = boost::iostreams::example;

    typedef
      io::code_converter<
        ex::container_source<std::wstring>
      >
      string_source;

    typedef
      io::code_converter<
        ex::container_sink<std::wstring>
      >
      string_sink;

    typedef io::stream<string_source> istringstream;
    typedef io::stream<string_sink>   ostringstream;
