I tried to duplicate the problems you mention in version 5.0 without success.
Perhaps you could forward specific info about how to duplicate the problem
such as the document, font size, and application you were using.

As a initial guess to such behavior I might offer the following explanation
and you can judge as to its applicability.  Some of the early bitmap fonts
were created with different characters in different point sizes.
That is, Chicago 12 point might contain the "missing" characters
while Chicago 18 point (or some other size) might not.  When
a document with 12 point Chicago is printed, the LaserWriter driver selects
the 18 point font to print (because it prints better at the higher resolution)
and ends up without the characters in question.  The practice of putting
different characters in different point sizes is discouraged, but you can
check this out very easily, just see if you have more than one point size of
Chicago in your font menu.

The Italic style variation also seemed to work fine for me.  Again by way of
explanation, the original LaserWriter contained a bug in PostScript where
italicizing a bitmap object such as a font character did not work when the
character being rendered was exactly the right size for printing and did 
not require scaling.  Again this is easy to test just by setting the point
size to some other size and see if the problem goes away.

Otherwise...  If there are additional comments or questions, you may
reply to me directly.
