title: Some octal-coded symbol characters can't work in gnuplot labeling
body: <p>I wanted to use the symbol of "\times" (we use in TeX) in gnuplot(5.0 in windows 8.1) labeling, and wrote the script including the following:</p>
  
  <pre><code>set term post eps enh
  set xl 'a{/Symbol \264}b'
  </code></pre>
  
  <p>\264 is the octal code of "\times", that I referred to <a href="http://materials.ucsd.edu/doc/ps_guide.pdf" rel="nofollow">ps_guide.pdf</a>.</p>
  
  <p>However, the font specification by /Symbol didn't work on \264, and "\cdot" like character was output instead of "\times". I also tried {/Symbol a} and {/Symbol \141}, and confirmed both output "\alpha" correctly. It seems that the octal codes greater than 220 can't find the corresponding /Symbol characters.</p>
  
  <p>Any ideas?</p>
