Do wcout and wcin work with GCC?

Do wcout and wcin work with GCC?

[Alex J. Dam]

  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
árvore
0

  Any help?

   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

   My system was built (mostly) according to LFS 4.0 on an AMD Athlon.
   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 depend on the platform as well as GCC.
