title: Gnuplot--Unicode characters with postscript terminal
body: <p>I want to print a per mil sign (‰) with Gnuplot. I am using postscript output terminal. I tried with 'set encoding utf8', and then call the per mil sign with {u+2030}. This does not work. </p>
  
  <p>I do not have pdfcairo available as an output terminal.
  Below are the available terminals on my MacBook Pro.
