Description Dave 2010-02-17 15:31:23 UTC 
When running GS version 8.14 and converting our PDF to a TIFF we can see some 
Greek characters that we can not see when taking the same PDF and converting it 
to a TIFF using 8.71.

Comment 6 Alex Cherepanov 2010-02-23 20:25:30 UTC 
This is some case of mixed-up encoding of in a TrueType font.
I'm taking over.

patch

Upgrade Adobe Glyph List to v. 2.0. 
AGL is used for character mapping in non-symbolic TrueType fonts in PDF files.

Many more characters, including Greek ones, are mapped correctly now.

The patch has been committed as a rev. 10822.
Regression testing shows no relevant differences. The different memory layout
affects one case of memory corruption.
