The platforms for which sizeof(wchar_t) == 2 (such as cygwin and mingw) 
or for which HAVE_WCHAR_T is not defined (possibly FreeBSD and others).

No, what I mean is that for the above systems we have the following typedef:
namespace lyx { typedef std::uint32_t char_type; }
so that if you have
   char_type var = 'a';
   os << var;
you will get "97" and not "a".
