Re: plotting points formatted iran utf8

Geoff

I have confirmed unicode state in postscript terminal in the beta ML.

Ethan answered to me :

https://sourceforge.net/p/gnuplot/mailman/message/37603807/

There exists not-simple way to use unicode in the postscript terminal.

From your reply, I understand you want use many symbols for plot.
Postscript terminal have prepared symbols. See the below

I am not a LaTeX user so that I cannot reply your interest LaTeX related matters.

Good Luck

Tatsuro
