locale -a displays the following:

john@john-desktop:~/Desktop/download/extract$ locale -a
C
el_CY.utf8
el_GR.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZW.utf8
POSIX
john@john-desktop:~/Desktop/download/extract$ 


==> Using these locales in the 3 of the 4 codes supplied, they work OK.


However the code number (3.) works only for "en_US.utf8", and it doesn't work
for "el_GR.utf8".


For "en_US.utf8":

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


int main()
{
    using namespace std;

    wcin.imbue(locale("en_US.utf8"));
    wcout.imbue(locale("en_US.utf8"));

    wstring ws;

    wcin>> ws;

    wcout<< ws<< endl;
} 


john@john-desktop:~/Desktop/download/extract$ ./main
Test
Test
john@john-desktop:~/Desktop/download/extract$ 


For: "el_GR.utf8"

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


int main()
{
    using namespace std;

    wcin.imbue(locale("el_GR.utf8"));
    wcout.imbue(locale("el_GR.utf8"));

    wstring ws;

    wcin>> ws;

    wcout<< ws<< endl;
} 


john@john-desktop:~/Desktop/download/extract$ ./main
Δοκιμαστικό

john@john-desktop:~/Desktop/download/extract$



As I said, the locales work in the 3 of the 4 codes supplied, but code number
(3.) doesn't.

So this isn't a "blocker" bug, but there is still a bug with wcin.imbue() and
wcout.imbue() when they are used alone without a 

"locale::global(locale("en_US"));"

or 

"ios_base::sync_with_stdio(false);"


statement.


wofstream works OK without any of the above statements.

For example the code:


#include <locale>
#include <string>
#include <fstream>


int main()
{
    using namespace std;

    wstring ws=
L"Δοκιμαστικό\n";

    wofstream file("filename.txt");

    file.imbue(locale("el_GR.utf8"));

   if(file.is_open())
      file<< ws;

}

works OK:

john@john-desktop:~/Desktop/download/extract$ g++ -ansi -pedantic-errors -Wall
main.cpp -o main
john@john-desktop:~/Desktop/download/extract$ cat filename.txt 
Δοκιμαστικό
john@john-desktop:~/Desktop/download/extract$
