Re: [Gnuplot-info] pdfcairo or pdf output font fails with Adobe Illustrator

Hi again

> If you can upgrade cairo to 1.12 (1.12.2 is current) that might help.

I decided to wait till Debian testing would get the upgraded versions
of cairo 1.12 and pango 1.30, which happened today. Not sure which one
did the trick, but everything works as expected now. I'm assuming it
was the updated pango.

I think the problem lies in this difference:

BEFORE:
$ pdffonts sample_plot.pdf
name                                 type              emb sub uni object ID
------------------------------------ ----------------- --- --- --- ---------
AGCFOR+ArialMT                       CID TrueType      yes yes yes      5  0

AFTER UPGRADE:
$ pdffonts sample_plot.pdf
name                                 type              emb sub uni object ID
------------------------------------ ----------------- --- --- --- ---------
BNNLMS+ArialMT                       TrueType          yes yes yes      5  0
MEXTZI+ArialMT                       CID TrueType      yes yes yes      6  0

Somehow, pango or cairo were not embedding the truetype 'type' that
Adobe Illustrator likes and thus it was seen as some unknown font.

The problem still exists in older versions of these libraries,
including the ones embedded in the windows gnuplot binaries. I tried
using gnuplot 4.6 for windows to replicate the problem and it happened
as well, so it's not a GNU/Linux centric problem.

Thanks for the help!

Best regards,
