New Revision: 8633

Modified:
   trunk/gs/src/zchar42.c
Log:
Fix (PDF interpreter): Improve omission of .notdef glyphs.

Details:
Bug #689757 "Extra square characters rendering PDF file".

Improvement to change 8217, makes the test for .notdef more
specific at Igor's suggestion.

Now matches exactly the string ".notdef" or strings beginning
".notdef~GS~" in order to include any .notdef modified by the
PDF interpreter when it appears multiple times in an Encoding.

EXPECTED DIFFERENCES:
None.
