title: How to handle python json dump if separator also present in json value
body: <p>I am using json dump in python with separtors like below:</p>
  
  <pre><code>json.dump(data, outputfile, sort_keys=True, indent=4, separators=(',', ':'))
  </code></pre>
  
  <p>But my data has few key value pairs in which itemseparator ',' is also present. I do not want to treat that as itemseparator </p>
  
  <p>For example:
  <em>{"withComma" : "1,23"}</em>
  This should be treated as
  <em>"withComma": ["1,23"]</em> and NOT as <em>"withComma":["1","23"]</em></p>
