The manual says that gnuplot is using libpdf and the way to use utf-8
encoded strings is to use a font which is also using utf-8 encoding.

But how do I find which fonts I can use or how do I make
gnuplot/libpdf search for a font in a given location?

Whatever font I'm trying to refer to (under /usr/share/fonts) results
in messages like:

Couldn't find font BitStream Vera Sans, falling back to Times-Roman
Couldn't find font FreeSans, falling back to Times-Roman

So what is the search path method used by gnuplot/libpdf?

I'm using Gentoo Linux

Thanks

To the best of my knowledge, only the commercial version of LIBPdf
(http://www.pdflib.com/) supports this.  The free version does not.

Fortunately, you can use the new pdfcairo terminal instead.
UTF-8 should "just work" in the cairo terminals, with no special
actions needed.

Thanks, that worked great! However pdfcairo was not included in my
current gnuplot (4.2 patchlevel 5), so I downloaded the latest CVS
version where it was supported. In what version was pdfcairo
introduced?

The cairo terminals are in 4.4, which has been available for testing
for some months with official release expected "real soon now".
