Test program:
#include <fcntl.h>
#include <errno.h>
int main()
{
char buffer;
int ok;
do {
ok = read(0, &buffer, 1);
printf("\ncode=%d %x errno=%d, ok=%d", buffer, buffer, errno, ok);
} while (ok > 0);
}
Output:
C:\cygwin\home\Juanjo\src\ecl\win32>chcp 936
Active code page: 936
C:\cygwin\home\Juanjo\src\ecl\win32>echo 亀 | foo.exe
code=-127 ffffff81 errno=0, ok=1
code=119 77 errno=0, ok=1
code=32 20 errno=0, ok=1
code=10 a errno=0, ok=1
code=10 a errno=0, ok=0
C:\cygwin\home\Juanjo\src\ecl\win32>foo.exe
亀
code=-127 ffffff81 errno=22, ok=-1
So it definitely seems that Windows's C library does not allow input ifrom
the console n other codepages?
