Summary: Error in codepageMap, codepage.c

Initial Comment:
Applies to expat v.1.95.8

>From MS:

"LeadByte:
Specifies a fixed-length array of lead-byte ranges, 
where the number of lead-byte ranges is variable. If 
there are no lead bytes in this code page, then every 
element of the array is NULL. If there are lead bytes in 
this code page, a starting value and ending value is 
specified for each range. Ranges are inclusive. The 
maximum number of lead-byte ranges for any code page 
is five. The array uses two bytes to describe each 
range, with a double-byte null terminator after the last 
range."

Note that "Ranges are inclusive". Therefore the function 
codepageMap should be changed:

for (i = 0; i < MAX_LEADBYTES; i+=2) 
{
  int j, lim;
  if (info.LeadByte[i] == 0 && info.LeadByte[i + 1] == 0) 
    break;
  lim = info.LeadByte[i + 1];
  for (j = info.LeadByte[i]; j <= lim; j++) map[j] = -2;
}
