Hello,
I just created the folder "fonts" and copied the "C:\Windows\Fonts\arial.ttf" into that, so I changed the line "D.AddFont('FreeSans.ttf', 'FreeSans-12' to "D.AddFont('arial.ttf', 'Arial", however, when I try to run the project, I get a SIGSEGV:
#0 WRPR_$SYSTEM_$$_TINTERFACEDOBJECT_$_IUNKNOWN_$_2_$_SYSTEM$_$TINTERFACEDOBJECT_$__$$__RELEASE$$LONGINT at :0 #1 ?? at :0 #2 ?? at :0 #3 ?? at :0 #4 WRPR_$SYSTEM_$$_TINTERFACEDOBJECT_$_IUNKNOWN_$_2_$_SYSTEM$_$TINTERFACEDOBJECT_$__$$__RELEASE$$LONGINT at :0 #5 ?? at :0
I also get some warnings and hints in the compilation:

Hm. This is strange, the code does not use interfaces at all.
The compilation hints/warnings do not really present me with a hint as to
what could be wrong.
Any chance to get a better stack backtrace ?
Michael.

Hm. I tried many PDF readers on the file. All unix based (okular,
openoffice), but also the Google docs PDF viewer and Firefox PDF reader.
All displayed the PDF just fine.
Can you send me the PDF you got ?

your file looks like the one I produced here when using "Visor de
documentos" which happen to be evince, this is what it looks
http://ctrlv.in/722669 the only change I did was adding JRAXX at the end
of every P.WriteText'd string where XX is the index of each instance.
Seems only latin text is working.
Later I will try with other readers.

Hmh. I can reproduce this error, but the file displays using Adobe Acrobat Reader 9.
OK, some more debugging/validation seems in order :/

I don't have the code with me so can't check now. But if the issue is
with Times related text, then FreeFont-ttf.zip should have nothing to do
with the issue you are experiencing. From memory, the FreeFont font is
used for the Unicode text only.
I'll take a look on my return in a week's time (if Michael doesn't beat
me to it). I'll retest with the latest Adobe Reader - clearly it is more
strict than older Adobe Reader versions.
If anybody knows of a online PDF validator (not a PDF Achive format
validator), that would help a huge amount.
Regards,
Graeme

Strange, because if I recall correctly it was tested with Cyrillic, and that worked ?

Please do, I'd welcome any hints as to what could be wrong !
(evince is one of the readers that was used to test, BTW)

I did some fixes for 3.0 prior to committing, and the test suites ran fine after that.

Applied in rev. 33176.
I added a fix for 2.6 compilation: no Default() intrinsic.
Thanks for the patch.
Michael.

The problem of evince not showing some texts it's because the compressed
font file stream size is written with an incorrect value. There is an
option to enable font file compression (poCompressFonts) but in the code,
compression is always enabled, the compressed stream size is returned in
the function that writes down the compressed stream, too late because the
/length item was already written using the uncompressed size. The attached
patch addresses both problems and makes sure length1 item is not written
down if not needed.
This however doesn't fix the Cyrillic and other texts :(
