title: Problems with saving to pdf file in Julia
body: <p>Good evening,</p>
  
  <p>I have a problem with formatting in pdf file after converting it from .jl (Julia file).</p>
  
  <p>For example, $ I_{1}, I_{2}, I_{3} $ <a href="https://i.stack.imgur.com/vEIsz.png" rel="nofollow noreferrer">illustration the error</a>  is not shown
  like a normal text. It is shown as the set of symbols, including $, _ , { , }. The headers are also shifted in pdf but in jl (Julia file) they are shown correctly.   </p>
  
  <p>How to fix this?</p>
  
  <p>Kind regards,</p>
  
  <p>Ilya</p>
