Printing unicode characters in PowerShell via a C++ program

powershell, unicode

Solution

From the printf docs:

wprintf and printf behave identically if the stream is opened in ANSI mode.

Check out this blog post. It has this nice short little listing:

#include <fcntl.h>
#include <io.h>
#include <stdio.h>

int main(void) {
    _setmode(_fileno(stdout), _O_U16TEXT);
    wprintf(L"\x043a\x043e\x0448\x043a\x0430 \x65e5\x672c\x56fd\n");
    return 0;
}

Problem

My end goal here is to write some non-latin text output to console in Windows via a C++ program. cmd.exe gets me nowhere, so I got the latest, shiny version of PowerShell (that supports unicode). I've verified that I can - type-in non-unicode characters and - see non-unicode console output from windows commands (like "dir") for example, I have this file, "가.txt" (가 is the first letter in the korean alphabet) and I can get an output like this: ``` PS P:\reference\unicode> dir .\가.txt Directory: P:\reference\unicode Mode LastWriteTime Length Name ---- ------------- ------ ---- -a--- 1/12/2010 8:54 AM 0 가.txt ``` So far so good. But writing to console using a C++ program doesn't work. ``` int main() { wchar_t text[] = {0xAC00, 0}; // 가 has code point U+AC00 in unicode wprintf(L"%s", text); // this prints a single question mark: "?" } ``` I don't know what I'm missing. The fact that I can type-in and see 가 on the console seems to indicate that I have the three needed pieces (unicode support, font and glyph), but I must be mistaken. I've also tried "chcp" without any luck. Am I doing something wrong in my C++ program? Thanks!
