title: Cannot display Unicode Characters (like λ) in PDF output of Jupyter
body: <p>I'm using Julia in a <code>jupyter notebook</code>. </p>
  
  <p>I want to generate a pdf for the results of my work. However, when generating the pdf, the <code>λ</code> of the mathematical expression <code>λ=3</code> is lost so that the output in the pdf is <code>=3</code>.</p>
  
  <p>Here is the jupyter notebook code</p>
  
  <pre><code>In[1]: λ=3 
  Out[1]: 3
  </code></pre>
  
  <p>Here is the pdf generated with the jupyter notebook</p>
  
  <pre><code>In[1]: =3 
  Out[1]: 3
  </code></pre>
  
  <p>This is not the case in with the pdf generated with <code>nteract</code> where the expression <code>λ=3</code> is fully printed out. However the overall appearance of the pdf generated with <code>nteract</code> is not as nice as the pdf generated with <code>jupyter notebook</code>. </p>
  
  <p>Here is printed pdf generated with <code>nteract</code> (looks exactly the same as the code itself): </p>
  
  <pre><code>In[1]: λ=3
  Out[1]: 3
  </code></pre>
  
  <p>Can somebody know how to print such character with <code>jupyter notebook</code>?</p>
  
  <p>Many thanks in advance</p>
