[Bug c++/35353] New: C++ wide character locale doesn't work

Sun, 24 Feb 2008 06:08:04 -0800 

The following code works:

#include <iostream>
#include <clocale>
#include <string>

int main()
{
    using namespace std;

    char *p= setlocale( LC_ALL, "greek" );

    if (!p)
      cerr<< "NULL returned!\n";

    wstring ws;

    wcin>> ws;

    wcout<< ws<< endl;
} 

[EMAIL PROTECTED] src]$ ./foobar-cpp 
&#916;&#959;&#954;&#953;&#956;&#945;&#963;&#964;&#953;&#954;&#972;
&#916;&#959;&#954;&#953;&#956;&#945;&#963;&#964;&#953;&#954;&#972;
[EMAIL PROTECTED] src]$ 



The following code DOES NOT work:

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

int main()
{
    using namespace std;

    wcout.imbue(locale("greek")); 

    wstring ws;

    wcin>> ws;

    wcout<< ws<< endl;
}
