Hi,everyone,

for example:

import std.stdio;
import std.process:executeShell;

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

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

void main()
{
	writeln("字符");
	executeShell("pause");
}
///////////////////////code end/////////////////////////////
In D2.078.1 It works very ok.
But After D2.080 ,It not works.
Who can help me?
Thank you.

In D2.078.1 It can display Chinese characters correctly! But After D2.080 , but it can't be used now. Who can help me? Thank you.

Ok,thank you. import std.stdio; import core.sys.windows.windows; import std.process:executeShell; extern(Windows) bool SetConsoleOutputCP(uint); void main() { SetConsoleOutputCP(65001); writeln("字符"); executeShell("pause"); }

How do I set the font? Please.

Create a shortcut to cmd.exe and edit its properties. The console 
window itself has a system menu for this too.

I known that. I need to set the font by the code now, because I need to do the installer, can't let this installer set the properties on each computer? Thank you.

That's so much code than next code. /////////////////////////////////////////////// extern(C) int setlocale(int,char*); static this() { import core.stdc.wchar_; import core.stdc.stdio; fwide(core.stdc.stdio.stdout,1); setlocale(0,cast(char*)"china"); } /////////////////////////////////// But After D2.078.1,it's not work.

What has that code got to do with setting the console's font? So you need to add more code to accomplish that.

You don't need to set the font to achieve the goal, why not?

This should work: const(char)[] toCodePage(const(char)[] s, uint codePage = 0) { import core.sys.windows.winnls, std.utf; foreach (char c; s) { if (c >= 0x80) { auto temp = s.toUTF16z(); char[] result; if ((result.length = WideCharToMultiByte(codePage, 0, temp, -1, null, 0, null, null)) != 0) WideCharToMultiByte(codePage, 0, temp, -1, result.ptr, cast(int)result.length, null, null); return result; } } return s; } void main() { import core.sys.windows.wincon, std.stdio; SetConsoleOutputCP(936); // Simplified Chinese codepage writeln("字符".toCodePage(936)); }

I've no idea, sorry. A quick scan of D's changelogs between those versions doesn't reveal anything relevant. But I wonder how your code ever worked - on Windows, calling setlocale with "china" returns null, which means it's not a valid locale, so did nothing. This does the right thing: extern(C) int _cwprintf(const(wchar)*, ...); void main() { SetConsoleOutputCP(936); _cwprintf("字符\n"); }
