[Bug 39297] kernel32.IsValidCodePage and friends don't support code page 708.

--- Comment #26 from Hin-Tak Leung  ---
Here is the full working version of the test code:

-----------------
#include <wtypes.h>
#include <stdio.h>

int main(void) {
  char inputbuf[1];
  wchar_t outputbuf[1];
  UINT CodePage = 708;

for (unsigned short c = 0; c<256; c++)
    {
      inputbuf[0] = (char)c;
      if (MultiByteToWideChar(CodePage, MB_ERR_INVALID_CHARS, inputbuf, 1,
outputbuf, 1) != 0)
        {
          printf("0x%02X 0x%04X\n", c, outputbuf[0]);
        }
    }
  return 0;
}
-----------------

You can cross-compile it with:

i686-w64-mingw32-gcc -Wall -o test.exe cp708test.c

then run with

wine test.exe

It just writes the mapping table out as a two-column table.

Change 708 to 1252 to test for code page 1252, etc if you wish.
