title: Symbols in gnuplot
body: <p>I thought I knew how the <code>{/Symbol x}</code> worked in gnuplot but I don't. I need to get a partial derivative symbol (utf8 code U+2202), and I can't. How could I do it. I haven't found anything online. This is the document settings:</p>
  
  <pre><code>set terminal postscript eps enhanced color font "Helvetica, 20"
  set encoding utf8
  </code></pre>
  
  <p>Thank you</p>
