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 http://tmacchant33.starfree.jp/Files/ps_symbols.pdf I am not a LaTeX user so that I cannot reply your interest LaTeX related matters.
