Unicode not working in wxWidgets Windows Console?

Post by AnotherCoder » Sun Aug 23, 2009 2:45 am

Hi, I am new to wxWidgets and am using it in Microsoft Visual C++ 2008. I can get this program from the Hello World Tutorial running just fine.

How come this program outputs question marks when I try to compile in release mode:

Code: Select all

#include <wx/string.h>

int main(int argc, char **argv)
{
	wxPuts(wxT("言語"));
}
This is the output:

Code: Select all

??

I already built wxWidgets libraries for Debug, Release, and Unicode - Release.[/code]

More likely "Unicode not working in Windows console". ;)

Unicode is not "very" supported in win console.
See if this article helps.

Thanks.
I will look at that link tomorrow.
Sorry, but I need to go now.

Will try to respond in less than 10 hours :oops:

EDIT: I updated the title in the first post.

I somewhat doubt you can use wx functions like this from "main" without wxWidgets being initialized first... not sure it's linked with your issue though

Okay, now I am even more confused. After reading the article, I got this far:

Code: Select all

#include <wx/string.h>
#include <wx/utils.h>
#include <windows.h>

int _tmain()
{
	//Store the old console format in 'oldcp'
	UINT oldcp = GetConsoleOutputCP();
	SetConsoleOutputCP(CP_UTF8);
	wchar_t s[] = L"aΣb";
	int bufferSize = WideCharToMultiByte(CP_UTF8, 0, s, -1, NULL, 0, NULL, NULL);
	char* m = new char[bufferSize];
	WideCharToMultiByte(CP_UTF8, 0, s, -1, m, bufferSize, NULL, NULL);
	wxPrintf("%S", m);
	delete[] m;


	//Restore the console format
	SetConsoleOutputCP(oldcp);
}
However, all I get is:

Code: Select all

Press any key to continue . . .
????????

Does printf (any kind of it..) work with capital 'S' ? I don't remember ever trying..

Also, are you sure that the font used to display the characters in the console has the glyphs for the ones you want to print?

Well, the guide I read said that I needed to change the font Lucida Console, but I don't know how to do this :oops:

Also, the article said to use "%S" because "it tells the wprint function to expect narrow string"

Thanks for all your responses.

Open a console, right click its title bar, choose Properties -> Font -> choose "Lucida Console" from the list there -> hit OK

Unicode in GUI?

Post by AnotherCoder » Sun Aug 23, 2009 6:25 pm

Okay, I've changed the font, but I am still only getting:

Code: Select all

Press any key to continue . . .
Well, I guess it is not so important to print Unicode in console. But, will Unicode work in normal GUI programs?

EDIT:
I'll just post a new topic with the Unicode in GUI applications:

Thanks.
