Description Jack Moffitt 2003-07-15 12:12:32 UTC
The attached test file fails to render properly in Ghostscript, but works fine
in Acrobat Reader 5.  All the glyphs show up as empty boxes in Ghostscript and
there are numerous messages like:

Substituting .notdef for V
Substituting .notdef for B
Substituting .notdef for P
Substituting .notdef for F
Substituting .notdef for parenleft
