title: Inconsistent reSt rendering with Sphinx
body: <p>I have the following reSt markup</p>
  
  <pre><code>==================  =====================
  **\\v**              vertical tab
  **\\\\**             backslash
  **\\'**              single quote
  **\\"**              double quote
  **\\?**              question mark
  ==================  =====================    
  </code></pre>
  
  <p>which renders <a href="https://cdn1.imggmi.com/uploads/2019/11/23/744c03eba5cd73cebd4f9687c12f7b24-full.jpg" rel="nofollow noreferrer">like this</a> with the online editor 
  <a href="http://rst.ninjs.org/" rel="nofollow noreferrer">http://rst.ninjs.org/</a>. However Sphinx renders it <a href="https://cdn1.imggmi.com/uploads/2019/11/23/8817d5f925943efdb8a33c867b403cb7-full.jpg" rel="nofollow noreferrer">like this</a> (note the missing backslashes on 2nd, 3rd and 4th rows). Why is this happening? How can I get the result of online editor with Sphinx?</p>
  
  <p><strong>Note:</strong> <em>imgur is banned in my country, that's why I have to give outside links to images.</em></p>
  
  <p>I'm using Python 3.7.5 from python.org on Windows 10, Sphinx 2.2.1 installed with pip.</p>
