I took one of the problematic files Bob sent me and added an Encoding object.
No go. For the fully embdedded font, Acrobat still thinks the font uses the
built-in encoding, and not a custom encoding. So the built-in encoding
is used, and, again, the duplicate entries are stripped. Foo!
> Finally, I have discovered if PDF file has a font which has no Encoding object
