Those use msvcrt.dll

Code Select Expand

#include<stdio.h>
#pragma comment(lib, "msvcrt.lib")

void  __stdcall ExitProcess(int);
int  __stdcall SetConsoleOutputCP(int);
void __cdecl mainCRTStartup(void) {
SetConsoleOutputCP(65001);
ExitProcess(main());
}

int main(void) {

    int στάσις = 1;
    στάσις++;
    printf("%d\n", στάσις);
    printf("%s", u8"δυσκατανοήτων\n");
    return 0;
}

Hmmmm ....  msvcrt.lib/dll is not included with PellesC.  You'll need a copy perhaps from MS Visual C, I see that I have it there, in C:\Program Files (x86)\DevStudio\VC\lib 

BTW I tried
fwprintf(stderr, L"%ls\n",L"δυσκατανοήτων");

didn't do much better.

Thanks  TimoVJL.

I couldn't get your code to work but the following did work 32 and 64 bit.

#include<stdio.h>
#include<windows.h>

int main(void) {
    SetConsoleOutputCP(65001);
    int στάσις = 1;
    στάσις++;
    printf("%d\n", στάσις);
    printf("%s", u8"δυσκατανοήτων");
    return 0;
}

@Ropert, console mode is a problem, font have to support more than basic ANSI.
@John Z, msvcrt.lib isn't part of Pelles C, but i was.

Hi Robert,

Here is how to create the import library, one for 32-bit and the other one for 64-bit programming :

polib.exe /MACHINE:x86 /OUT:msvcrt.lib C:\Windows\SysWOW64\msvcrt.dll

polib.exe /MACHINE:x64 /OUT:msvcrt.lib C:\Windows\System32\msvcrt.dll

In this example, it's assumed that you are operating under a 64-bit system.

For 32-bit OS :

polib.exe /MACHINE:x86 /OUT:msvcrt.lib C:\Windows\System32\msvcrt.dll

Hi Vortex:

Thank you for that useful information.

I do prefer a native Pelles C solution.

Still, it would be nice to be able to do

Code Select Expand



printf("%s", "δυσκατανοήτων");



without the u8 prefix, as is possible now in the newer versions of CLang and GCC.

[TimoVJL]

Console have to use Lucida Console or Consolas or similar TT font.

[Robert]

Sometimes I wonder, is it me or is it IT ?

Today, without the u8 prefix on the quoted string literal, the code below does execute as expected when compiled with Pelles C and with the console codepage set to 65001 and with a console font containing Greek alphabet glyphs.

It's IT! 
The MS console is the worst ever wrote piece of s...oftware when multilingual support gets in... 

[Pelle]

Since Pelles C is for Windows, the most obvious default runtime character set is/was "ANSI" (when no string prefix, for compatibility reasons) -- but this also means the "ANSI" character set that is in effect when compiling the source file(!)

This is far from perfect, but I'm not sure how to change the default without breaking old programs...
