#2328 — UTF-8 encoding

I have problems making UTF-8 characters be printed correctly in a png term.
My whole system is configured to process everything in UTF-8.

My understanding is that setting "set encoding utf8" in gnuplot should do
the trick. Alas, it doesn't. I also tried "set encoding locale" and whatnot,
but to no avail.

For this too I use a workaround; instruct my editor to create an ISO Latin9
output. And here, once again, I'd of course prefer a correct solution to my
hack. What did I miss?

(I seem to faintly recall that I didn't have that problem with gnuplot 4.2,
but since switching to 4.4 - now I'm using 4.6 - I noticed it.)

Forgive me my primitive questions, I am only a casual user of gnuplot, and
a lot of things that at first glance gave me the impression to have to work
in a simple way; yet I notice a lot of basics that seem to behave strangely.
And in the voluminous manual I also couldn't find any enlightening hint.

It is not the UTF-8, it is the default font gnuplot is using, just set it explicitly (Even using path to TTF file should work, AFAIR).
This works for me:

gnuplot -e 'set term png font "Arial Unicode MS"; set xrange [0:2*3.14]; plot sin(x) w l title "Това е синус,ブルガリ語で"' >a.png; display a.png

Kalin.
