FrankLike (5/23) Jan 23 2019 In D2.078.1 It can display Chinese characters correctly!

FrankLike (6/8) Jan 25 2019 I known that.

FrankLike (15/21) Jan 25 2019 That's so much code than next code.

Hi,everyone,

for example:

In D2.078.1 It works very ok.
But After D2.080 ,It not works.
Who can help me?
Thank you.

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.

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) {

       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");
   }
