Re: [Mingw-users] putwchar not working

[Hisham S. <sue...@ya...>]

I totally agree and the following simple experiment proves it:
#include <stdio.h>

int main() {  char s[] = "\xEC\xAC\x9F\xEA\n";
  char * t = s;  while (*t != '\0') {   putchar (*t);   t++;  }  return 0;}
This program has in s my first name in Arabic encoded using code page 720. According to the command window properties this is the current code page on my computer. However I still get garbage.When I redirect the output to a file then display this file using notepad++ I get garbage, but when I change the encoding to "OEM 720", it displays correctly... hisham...

The problem is that GCC treats the file source as UTF-8, but the puts
function can accept only an ‘ANSI’ string. The conclusion is the same
as yours: removing ‘u8’ and saving the file as the ‘ANSI’ code page
should work.

As discussed earlier, putws does not work. Otherwise, putws(L"هشام\n")
is the logical solution on Windows.
