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

[Andres C. <aci...@gm...>]

Hi gnuplot users,

I've been experiencing this very annoying problem with some of the
plots I produce with gnuplot (happens on both 4.4.0 and 4.6.0).

I produce the plots on a GNU/Linux system, specifically Debian
testing, using either the pdfcairo or pdf terminals. I set fonts to be
Arial. They look great on any pdf viewer I've checked. Furthermore the
files open just fine in Inkscape and the font is properly detected as
Arial.

The nature of academic work requires cooperation. Some of these people
hold Adobe Illustrator in high regard and they use it extensively for
editing plots. Whenever I try opening my plots produced by gnuplot via
any of the above mentioned pdf terminals, in Illustrator (on a Windows
computer) it gives me an error saying that DejaVu Sans and Bitstream
Vera fonts cannot be found and they will be substituted by the closest
equivalent. Unfortunately the text becomes a bunch of squares with and
"X" in the middle.

This is very annoying. I can work around the problem using the
postscript terminal. The font of the eps files produced this way works
fine in Adobe Illustrator and other editors and viewers.
Does anyone understand the problem here and how to get around it
without having to use eps files?

I don't want to have to resort to eps files. I will give cairolatex a
try tomorrow and see if the situation improves. Any tips is welcome.

Cheers

Andres
