digitalmars.D.learn - How to print Chinese characters in console in window XP?

reply Sam Hu <samhudotsamhu gmail.com> writes:
In DMD2030 I just found that Chinese characters the like can not print properly
into console.

//Below code does not show output properly in windows console:
void main()
{
wstring country="中国";
writefln(country);
}



Is this an OS issue or is there any way to reach the goal?

Thanks in advance.

It's an OS issue.  Someone asks about this once every two weeks.  You
have to set up cmd.exe to use Unicode.  You have to change the fonts
to Lucida, I think, and use 'chcp 65001' before running your program.

Thanks so much for your help.
Below is my try:
1.source(wrote in notepad.exe)

module test;
import std.stdio;
import std.c.windows.windows;
extern(Windows) {BOOL SetConsoleOutputCP(UINT wCodePageID);}

void main()
{
SetConsoleOutputCP(65001);
wstring country="中国";
writefln(country);
}

2.set notepad font Lucida Console (acutally tried Lucida Sans Unicode also);
3.Save test.d in Unicode (actually also tried UTF-8);
4.Compile and run.But the output still doesn't make sense.

Regards,
Sam

Well I don't know how else to help, I just know that cmd.exe sucks
when it comes to Unicode :\

Sorry to have to disappoint you, but Chinese output to a Windows console
is non-trivial if not entirely impossible (you'd probably have to ask
someone using a Chinese Windows version for a definitive answer).

Your approach will work for more common unicode characters, like eg. the
greek alphabet, the problem is that the fonts included with your
standard Windows just don't come with Chinese glyphs.

In theory you *could* hack the registry to enable different fonts for
the console (HKLM/SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Console\TrueTypeFont, add a string entry named 00,
000, 000 etc. and your desired font as value), but you'd still have to
find a font including Chinese glyphs which works for this purpose. There
are fonts like for example GNU unifont and something called SimSun from
Micro$oft which contain these glyphs, but to my knowledge none these
work in the console.

So the short answer is no, afaik there isn't any practical way to get
Chinese output in the Windows console.

No, it's not.  In Python, unicode text output just plain works.

Program:

  print u'涓浗'
Output:
  涓浗

This is a bug in D, full stop.

(Yes, you do need to to set a codepage that contains these characters (I
am using CP932) and you need an font that can represent these
characters.  I assume OP already has both.  Note that CP65001 does not
work.)

I'm having troubles with this ...


C:\temp>chcp 932
Invalid code page
C:\temp>chcp 65001
Active code page: 65001

It seems that my Windows XP doesn't know about CP932.

Yeah, it looks like some more setup work is required.  I got the same
error message when trying to use CP932 or CP950.  Under Windows XP, in
Regional and Language Options under the control panel:
  - On the Languages pane, make sure East Asian languages checked.
  - On the Advanced pane, make sure that the code pages you want to use
are checked.
  - Also on the Advanced pane, you may need to select the language you
want to use as the language for non-Unicode programs.

However, I assume that the OP already has his computer set up to support
Chinese characters from the console, or he wouldn't be asking this
question.  I can confirm that on my computer, unicode text output works
in Python but not in D.

While it certainly wasn't my intent to spread false info, nor to defend
D or sidetrack from its bugs, I cannot confirm that unicode output *just
plain works*, neither with Python, and I'd be highly interested in more
info on how you got it to work. CP932 is invalid on my machine as well,
and I don't know of a font that supports Chinese symbols and is
available for the Windows console. Could you post some further clues
like which font and which version of Windows you use, please? That'd be
highly appreciated, thanks in advance.

Dear All:

Thank you so much for all your help!

Yes,I am using xp+sp3 Chinese version and can print Chinese font in the console
in C++ program:

#include <iostream>
int main(int argc,char* argv[])
{
std::cout<<"中国"<<std::endl;
return 0;
}

There are two separate issues here.  One is unicode output (which
involves translating unicode text to the encoding used by the console).
 The other issue is having a console window that can display the
characters that you want to display.

The former can be tested without resorting to exotic code pages.  Try to
 output '亩' in CP775 or '陌' in CP857.  Both of these code pages are
readily available.

To enable Chinese characters, some more work is necessary.  Under
Windows XP, Control Panel, Regional and Language Options:
  - On the Languages pane, make sure East Asian Languages is checked.
  - On the Advanced pane, select a language that uses Chinese characters.
  - On the Advanced pane, make sure that the code pages you want to use
are checked.

Thanks for your clarification.
The problem is that, unless you set up your system to use Chinese for
every non-unicode-ready application, systemwide and for all users, you
will not get Chinese character output in the Windows console.

The downside is that setting up your OS in such a way tends to render
the user interface of a lot of other applications unusable if Chinese
isn't your everyday language.

For a lot of us this isn't very practicable, eg. having my German
umlauts replaced with Chinese glyphs isn't exactly what I have dreamed
of all my life.
That's what I meant with the changes not being trivial, and your
response sounded a bit like I was talking nonsense and getting it to
work was a piece of cake, and I naturally was curious whether there was
a simple solution. While being a bit disappointing, thanks for
straightening out that this isn't the case.

Nonetheless there apparently is a bug here if D/Phobos with its supposed
unicode support isn't capable of producing output which is possible with
Python or even olde C++.
