Description Marcos H. Woehrmann 2010-06-21 20:17:20 UTC 
The customer reports and I've verified that reading the attached PDF file with gs head (r11410) results in several warnings messages and incorrect output (as compared to Adobe Acrobat Reader 8).

The command line I'm using for testing:

  bin/gs -sDEVICE=ppmraw -o test.ppm ./PDF_PosWord.pdf

The messages printed by Ghostscript:

patch

Some of the fonts in the sample file are missing /.notdef glyph and
were rejected by PS interpreter. This caused an attempt to load the font
by the name, which didn't match the text.

The patch adds /.notdef entry to it it is missing from an embedded PDF font.

With this patch the font can be loaded but the characters still look
distorted.
Comment 3 Alex Cherepanov 2010-06-22 05:25:29 UTC 
Wendy confirms that Adobe Acrobat renders some of Japanese characters
in the sample file incorrectly. Acrobat Reader 5 shows somewhat
better picture, but it's still wrong. 

Ghostscript shows exactly the same picture as Acrobat Reader 8.
Since Ghostscript matches Acrobat Reader 8, no further actions
are needed.

The patch for missing /.notdef has been committed as a rev. 11412.
