Question

How to write unicode character farsi in c++ in ms-dos?

cout<<"Helo world"<<"سلام جهان";

Answer 1

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

int main()
{
      using namespace std;
      wstring wcs = L"中文";
      locale old = wcout.imbue(locale("") ); // "" is environment's default locale
      wcout<<wcs<<endl;
      wcout.imbue(old );                     // restore old locale
}

Answer 2

You need to convert the string to proper codepage. MS-DOS codepages are named like CP437, with CP followed by three digits. Notice that normally only less than 256 different characters may be displayed and thus many Unicode characters just cannot be shown in text mode.

using namespace std;
setlocale(LC_ALL, "fa-IR");

time_t rawtime;
struct tm * timeinfo;

time(&rawtime);
timeinfo = localtime(&rawtime);

struct lconv * lc;
lc = localeconv();


LOGFONT * tFont;
tFont = GetFont();

CFont font;
VERIFY(font.CreateFont(
    tFont->lfHeight,                    // nHeight
    tFont->lfWidth,                     // nWidth
    0,                                  // nEscapement
    0,                                  // nOrientation

pdc->SetBkMode(old);
// Done with the font.  Delete the font object.
font.DeleteObject();

Answer 4

you can use wchar_t instead of char.

and you should use wcout instead of cout too.

if your console support unicode this will work. another way for Iranians was a software called "vegaf" but its for much years ago and i forget it.
