Many people want to display their string(ANSI),but always to convert string by

'toMBSz',and it can't convert to immutable char[],it's difficult to display their ANSI

string in CMD.EXE.

We can use 'chcp 65001',but for exe'consumer,it's difficult to use.

Now,I find a function,if add it in 'writeln' function,D will very be popular!

string toMBS(string s, uint codePage = 0)
{
		// Only need to do this if any chars have the high bit set
	foreach (char c; s)
	{
		if (c >= 0x80)
		{
			char[] result;
			int readLen;
			const wchar* ws = std.utf.toUTF16z(s);
			result.length = WideCharToMultiByte(codePage, 0, ws, -1, null,

0,null, null);

			if (result.length)
			{
				readLen = WideCharToMultiByte(codePage, 0, ws, -1,

result.ptr,result.length, null, null);
			}

			if (!readLen || readLen != result.length)
			{
				throw new Exception("Couldn't convert string: " ~

sysErrorString(GetLastError()));
			}

			return cast(string)result[0..$-1];
		}
	}
	return s;
}

Now ,I use it :

string toStr(string s)
{
   return toMBS(s,0);
}
writeln(toStr("中文"));

So difficult！

What do you think？

But .. some people switch cmd.exe to utf8, so you'll break them.

http://superuser.com/questions/269818/change-default-code-page-of-windows-console-to-utf-8

not to mention all the linux people it'll break.

Perhaps:

import std.windows.charset;
import std.conv;

then:

writeln(to!(string)(toMBSz(utf8)));

Why not switch by Version:
version(Windows)
{
   writeln(to!(string)(toMBSz(utf8)));
}
else version(linux)
{
  ...
}

writeln(to!(string)(toMBSz("中文1")," ",to!(string)(toMBSz(中文2));

Can't easy to do:
writeln("中文1"," ","中文2");

We can use 'chcp 65001',but for exe'consumer,it's difficult to use.

Exe'Consumer! they are difficult to use!

Why we can not simply automatically switch CMD to UTF-8 before app start?
I do not see any minuses in this solution.

you can provide .bat file that will change codepage and run your exe.

Windows console is broken, I recommend using API functions (WriteConsole) instead.

Well, that function writes to the windows console.

+1. I use

import std.stdio;
import std.c.windows.windows;

void main()
{
    SetConsoleOutputCP(65001);
    writeln(utf-8 text);
}
