Hi,

My first D program is like this:
-----------------------------------
import std.stdio;

void main(string[] args)
{
       dstring s1 = "hello你好"d;
       writeln(s1);
}
-----------------------------------
But the output is not correct(and my console codepage is 936):

C:\D\dmd2\samples\d>dmd hello.d -offilename hello.exe
C:\D\dmd2\samples\d>hello.exe
hello浣犲ソ

thanks.

Hi,
I tried your code and it works fine for me. I think the windows 
console only supports UTF-16, try using wchar/wstring instead of 
dchar/dstring.

Thanks, my problem has been solved:)
---------------------------------------
import std.stdio;
import core.stdc.wchar_;

extern(C) int setlocale(int, char*);

static this()
{
    fwide(core.stdc.stdio.stdout, 1);
    setlocale(0, cast(char*)"china");
}

int main(string[] args)
{
	string s1 = "hello你好";
	writefln("%s", s1);
	return 0;
}

This solution has a problem, look at this：

add such code is better than use 'chcp 65001' for exe's consumer.

extern(C) int setlocale(int, char*);

static this()
{
	import core.stdc.wchar_;

    fwide(core.stdc.stdio.stdout, 1);
    setlocale(0, cast(char*)"china");
}

-----------------------------------------------------------------------
module cnsetlocale;

import std.stdio;

extern(C) int setlocale(int, char*);

static this()
{
	import core.stdc.wchar_;

    fwide(core.stdc.stdio.stdout, 1);
    setlocale(0, cast(char*)"china");
}

void main()
{
	printf("a！！\n");
	writefln("%s","hello,中文！！");
	string msg="你好！！";
	string msg1="去看电影吗？";
	string msg2="是吗？";
	a(msg2);
	writefln("the string is %s \n %s %s
and %s",msg,msg1,msg2,"你要去哪儿玩？");
	writeln("公园？","  电影院？");
	readln;
}
void a(string msg2)
{
	writefln("the string is %s",msg2);
}
------------
dmd hello //only such simple

'printf' is error,but for consumer is better,because they don't 
need  change any things,so don't use the 'printf' function .

If only test for yourself,you can add such codes for your main :

	import std.process;
	executeShell("chcp 65001");

then,change the Font to 'Lucida Console'

after 'dmd hello'

( if you don't want use 65001,then open cmd,chcp 936 ,and change 
the Font to '宋体')

ok.
