Hi,

the current draft n3000 defines wstring_convert (22.3.3.2.2 - 2) with
two types (byte_string and wide_string):


namespace std {
   template<class Codecvt, class Elem = wchar_t,
    class Wide_alloc = std::allocator<Elem>,
    class Byte_alloc = std::allocator<char> > class wstring_convert {
   public:
    typedef std::basic_string<char, char_traits<char>, Byte_alloc> byte_string;
    typedef std::basic_string<Elem, char_traits<char>, Wide_alloc> wide_string;


Is the second one correct? I think it should be

    typedef std::basic_string<Elem, char_traits<Elem>, Wide_alloc> wide_string;




Regards,

Daniel Vogelbacher

The latter is correct. The problem is an editorial oversight, because
the intended change is documented in:
