[lucida] Bug in lucida ligature handling

Dear Karl,

I appear to have 2 versions of the fonts (although they claim to have
been created at exactly the same time..., but the bounding box is different)

%!PS-AdobeFont-1.1: LucidaBright 1.008
%%CreationDate: 1993 Aug 11 14:19:28
/FontBBox{-286 -211 1014 967}readonly def
/UniqueXX 5029001 def

%!PS-AdobeFont-1.1: LucidaBright 1.009
%%CreationDate: 1993 Aug 11 14:19:28
/FontBBox{-286 -211 1014 928}readonly def
(no Unique id in here)

The problem also occurs with the outline versions of the cmr fonts.

You are probably right about the fact that not the full fonts are
embedded in the .ps.

What I cannot explain is that a run of ps2pdf in 1999 over the .ps file
produced a .pdf file that Bluebeam PDF Revu correctly displays, while a
run of ps2dpf (or Distiller) in 2012 does not...

I will contact BlueBeam supprt as well of course, but the reason I also
contacted you guys is because this seems to be related to the way
encodings are handles either when generating the .ps or when generating
the .pdf. Note that when using pdflatex to generate the .pdf directly,
the problem does not appear.
