   Well, it might still be a macro that, for example, translates the   
   literal to a function call producing a reference to a value/array of the   
   strongly typed character type, e.g. like the U macro defined below:   
      
      
      
   #if     CPPX_NATURAL_ENCODING == CPPX_ENCODING_UTF16   
   #   
       CPPX_STATIC_ASSERT( sizeof( wchar_t ) == 2 );   
   #   define CPPX_U_ENCODING ::progrock::cppx::u::Encoding::utf16   
   #   define U( aLiteral ) ::progrock::cppx::u::typed( L##aLiteral )   
   #   
   #elif   CPPX_NATURAL_ENCODING == CPPX_ENCODING_UTF8   
   #   
   #   define CPPX_U_ENCODING ::progrock::cppx::u::Encoding::utf8   
   #   define U( aLiteral ) ::progrock::cppx::u::typed( aLiteral )   
   #   
   #else   
   #   error "The natural encoding for this OS is not supported, sorry."   
   #endif

   I did that about two months ago, . Beman Dawes wrote then   
   "If you care enough to open a ticket on the Boost bug tracker, I'll move   
   the V2 code to V3. But there is a big backlog of tickets, so no   
   guarantees as to when that will happen." Which seems to mean that it'll   
   be fixed Real Soon Now(TM), to quote Jerry Pournelle from his Chaos   
   Manor articles in BYTE magazine.
