title: How is @ produced in gnuplot?
body: <p>I'm trying to put as the title of a plot "P@10" using GnuPlot, using the Helvetica font.</p>
  
  <p>What I did was this:</p>
  
  <blockquote>
    <p>set encoding iso_8859_1</p>
    
    <p>set title "P \100 10"</p>
  </blockquote>
  
  <p>The \100 comes from the octal representation of the at symbol in <a href="http://www.fileformat.info/info/unicode/char/0040/index.htm" rel="nofollow">unicode</a>. The final plot, however, replaces the @ with a simple space. Other symbols work as expected.</p>
  
  <p>I also tried the matlab script provided <a href="http://judsonsnotes.com/notes/index.php?option=com_content&amp;view=article&amp;id=629%3asymbols-in-gnuplot&amp;catid=48%3aengineering&amp;Itemid=69" rel="nofollow">here</a>, to look for the @ symbol in at least 4000 different codes, but I couldn't find it.</p>
  
  <p>Is this possible, even with another font?</p>
  
  <p>EDIT: I tried this on three different systems, Ubuntu AND Windows, to no avail..</p>
  
  <p>EDIT2: Minimal working example:</p>
  
  <blockquote>
    <p>set term postscript eps enhanced color</p>
    
    <p>set encoding iso_8859_1 </p>
    
    <p>set title "Test \@ Test" -or-     set title "Test \100 Test"</p>
    
    <p>set out "example.eps"</p>
    
    <p>plot sin(x)</p>
  </blockquote>
  
  <p>My output doesn't have any @ sign in the title.</p>
