CP1252 character entities missing in in HTML 4.01

I just noted that while

  http://www.w3.org/TR/html4/sgml/entities.html

claims that HTML 4.01 provides character entities for *all*
CP1252 characters, I couldn't find the entities for the following
CP1252 characters listed on

  http://www.microsoft.com/GLOBALDEV/Reference/sbcs/1252.htm

8E = U+017D : LATIN CAPITAL LETTER Z WITH CARON
9E = U+017E : LATIN SMALL LETTER Z WITH CARON

Is there a good reason for this omission or is it just a bug in the
spec?

See

  http://www.cl.cam.ac.uk/~mgk25/ucs/CP1252.html

for the obvious character entity names that I would suggest to be added.
