  OK, you guys need not tell me why it's not working on my system.
  I just wish to know whether it should work or if it's not working
only on my system.

  thanks

   I don't know which packages' versions are relevant. My glibc is 2.2.5,
g++ is 3.3.1.

What platform are you trying this on?  Wide character support may

Subject: Do wcout and wcin work with GCC?

  Hi,

  I would like to use C++ as my primary language for computer
programming, but I'm having some problems dealing with
multi-byte strings in g++.
  How can I make wcin and wcout work? Whenever I read a string
 from the console the string is truncated at the first non-ASCII
character. When I'm writing to wcout, the string is also
truncated.
  I've tried imbue(), setlocale(), etc. but it didn't solve my
problem.
  My locale is pt_BR.UTF-8, my gcc and g++ are version 3.3.1.
  EXAMPLE:

#include <iostream>
#include <string>
#include <locale>

using namespace std;

int main(){
   locale l("pt_BR.UTF-8");
   setlocale(LC_ALL, "pt_BR.UTF-8");
   locale::global(l);
   wcout.imbue(l);
   wcin.imbue(l);
   wstring s;
   wcin >> s;
   wcout << s.length() << endl;
}

Some output:
$ ./prog
arboris
7
$ ./prog
Ãrvore
0

  Any help?
