Adobe posted a new spec. sometime back in March.  It is listed in
Appendix C.  I know, I just checked so I wouldn't get egg in my face.

Right.  I brought that up to illustrate when something that is
deprecated should not be supported, and when another deprecated thing
should be supported.  See below...

I see that you don't "understand" my reason.  I just produced an
example with Distiller 4.0 in which a Type 1 font (when embedded as a
CFF font) used this modified endchar.  The original font used seac for
the accented character, and a lot of fonts do so; moreover, think of
how many Distiller 4.0 produced PDF files are out there.  Now, what
happens if someone writes a PDF viewer that uses FreeType (not an
unlikely proposition), and all of a sudden gets foobar results when
viewing such a embedded CFF font?

Hm... indeed!

Oh goody!
