wprintf does not work correctly.

[edison]

SetConsoleOutputCP(65001) does not work, but 936 works.

#include <stdio.h>

int main(void)
{
wchar_t *a = L"中文";
DWORD n;
SetFileApisToOEM();
SetConsoleOutputCP(936);
WriteConsoleW(GetStdHandle(STD_OUTPUT_HANDLE), a, wcslen(a), &n, NULL);

wprintf(L"%ls\n", a);
wprintf(L"%ls\n", L"中文");
return 0;
}

output:
Win 8.1 x64 chs:

中文-?
-?

the wprintf still not work in right way.

Something like this works?

char MbStr[32];
WideCharToMultiByte(936, WC_DEFAULTCHAR, L"中文", -1, MbStr, 32, NULL, NULL);
printf("%s\n",MbStr);

WideCharToMultiByte(936, WC_DEFAULTCHAR, L"中文", -1, MbStr, 32, NULL, NULL);
printf("%s\n", MbStr);
return 0;
}

Have you created this as a windows project or a console project?

Add '-subsystem:windows' on linker command line or select subsystem=windows form linker tab.

Thanks. Adding user32.lib, enabling M$ extensions and changing to sub windows made it finally work. Would be great if the IDE was able to guess these settings automatically, or at least throw warnings of the "wWinMain detected - are you sure it's a console app?" style...

Ya it seems that the low level part of a file writing on printf family is unaware of encodings and codepages. This probably lead to mishandling of strings.

The wprintf of POCC 8.0 RC5 still not work correctly, nothing changed here.

[frankie]

Yes, Pelle want the IO subsystem to comply with Cxx standard, while MS subsystem is not compliant...

[edison]

Still not works in 8.0 RC6.
Is there any chance to fix this problem in furture version ?
