   Multibyte encoding is allowed but not ``supported''.   
      
   2.14.5/15:   
    ... Note: The size of a char16_t string literal is the total number   
    of code units, not the number of characters ...   
      
   The problem with wchar_t is that its range is limited by the locale.   
   So if we need a portable and fully Unicode-supported string, char32_t   
   should be used instead.
