title: Splitting up a line in a HOCON file
body: <p>I have file in HOCON format where a very long string is assigned to a key. The string contains single quotes (and other "illegal" characters), and hence I need to enclose the value in double quotes. Something like this:</p>
  
  <pre><code>key="extremely long string with 'illegal' characters :;/. bla bla ..."
  </code></pre>
  
  <p>For readability, I would like to split this up into multiple lines. I simple have not found a way to do this. If the string weren't enclosed by double quotes, I could use <code>\</code> to split lines. And if I didn't care about adding newlines, I could use <code>"""</code>. But I <em>do</em> care about these things.</p>
  
  <p>I have studied the <a href="https://github.com/typesafehub/config/blob/master/HOCON.md" rel="nofollow" title="the informa HOCON specs">informal HOCON specs</a> but have still not found a solution.</p>
  
  <p>(Since HOCON resembles JSON (which I don't know anything about), I have tagged this question with "JSON" as well.)</p>
