title: Problem saving greek letters in normal style while exporting as .pdf [MATLAB]
body: <p>I am having trouble generating greek letters as normal style while exporting in <strong>.pdf</strong> format while <strong>.fig</strong> and <strong>.png</strong> formats have no issues doing so.</p>
  
  <p>Once the figure is generated, this is how</p>
  
  <pre><code>x = 0:pi/100:2*pi;
  y = sin(x);
  
  figure('name','test');
  plot(x,y);
  xlabel('d [\rm{µ}m]'); 
  ylabel('\eta');
  legend('d = \rm{µ}m');
  
  print( '-dpdf', '-painters', 'test')
  </code></pre>

  <p>Could someone explain why am I having these issues only with the <strong>.pdf</strong> format? </p>
  
  <p>And how to fix the problem?</p>
