wcout, wprintf() only print English

[Ioannis Vranos]

Has anyone actually managed to print non-English text by using wcout or
wprintf and the rest of standard, wide character functions?

Are you sure that you stored your source file in the same encoding the
compiler expects as source character set?

Well I created the file with anjuta editor with the message being a
Greek one. The Greek message also appears the same when I display the
source file in the console.

I suppose it is saved as UTF8.
Also the code

#include <iostream>
#include <string>

int main()
{
using namespace std;

wstring s;

wcin>s;
wcout<< s<< endl;
}
displays nothing when I enter greek text.
Should I mess with locales?

both in g++ under Linux and VC++ 2008 Express under Windows, with the
latest saving the source code file as Unicode after it detected
non-english text.

Hmmm... I work almost entirely in English, so this error message is new
to me:

$ make
g++ -ansi -pedantic -Wall main.cc -o main
main.cc: In function 'int main()':
main.cc:4: error: converting to execution character set: Invalid or
incomplete multibyte or wide character
make: *** [main] Error 1

I don't remember anymore the details but the problem has something to do
with codecvt: Your wide characters are automatically converted to narrow
characters by wcout. This is something you might not want (and even if you
want it the conversion might not work automatically the way you expect :).

Try writing to wstringstream and converting to UTF-8 explicitly (storing
the result eg. in string). If your console supports UTF-8 you can print to
cout (otherwise print to a file so you can test the output in an editor).

HTH,
Boris

Perhaps when you copy and paste the greek text, you copy garbage (that
is, not viewing the message in the correct character set in your
newsgroup reader).
So, I repost the code in this message which is encoded to Unicode (UTF-8):
#include <iostream>

int main()
{
using namespace std;

wcout<< L"Î”Î¿ÎºÎ¹Î¼Î±Ï ƒÏ„ικό μήνυμα\n" ;
}

Thanks, you were correct.

Here's what I thought was "supposed" to be the portable solution:

#include <iostream>
#include <locale>

int main() {
std::wcout.imbu e(std::locale(" el_GR.UTF-8"));
std::wcout << L"Î”Î¿ÎºÎ¹Î¼Î±Ï ƒÏ„ικό μήνυμα\n" ;
}

However, my system still shows question marks for this. For whatever
it's worth, here's the (probably incorrect) way that appears to work on
my system:

#include <iostream>
#include <locale>

int main() {
std::cout.imbue (std::locale("" ));
std::cout << "Δοκιμασ τικό μήνυμα\n" ;
}
