Yes, I believe that it is only when there is << and no
encoding file that pdftex forgets to make an encoding object,
and in this case the printing problem is acrobat's fault.

I don't have one anymore.
As I recall, a long time ago we had to specify encoding files;
so I guess we had such a list once! (There were problems caused
by the fact that bakoma has different names for some of the
glyphs -- e.g. the pounds sterling symbol is called "dollar".
It was a relief to be able to dispense with the enc's.)
