That chart seems to be wrong or outdated. In modern windows, code point 243 -
248 are definitely used, AFAIK. See the attached table to this bug.

On real windows, you can probably write a little program to dump the mapping
table for code page 708, by doing something like this:

------------------------------------------
char inputbuf[1];
wchar_t outputbuf[1];
UINT CodePage = 708 ;

for (ushort c = 0; c<256; c++)
{
inputbuf[0] = (char)c;
if (MultiByteToWideChar(CodePage, MB_ERR_INVALID_CHARS, inputbuf, 1, outputbuf,
1) != 0)
            {
                // dump c and outputbuf[0] in two columns
            }

}
-----------------------------------------

and hopefully it should result in something identical to what I attached.
