title: Special characters in DataTable column names in JQuery/Javascript
body: <p><strong>EDIT</strong> : I have created this <a href="https://jsfiddle.net/dcweca05/" rel="nofollow noreferrer">fiddle</a>
  that shows the issue.</p>
  
  <p>I define my columns the following way (pseudo-code, please don't tell me to declare the variables)</p>
  
  <pre><code>var cols = [];
  cols.push({
      data:theNameWithSpecialCharacters,
      title:theNameWithSpecialCharacters,
      render: $.fn.dataTable.render.number(",",".",3)
  });
  
  myDataTable = $('#theDataTable').DataTable({
      columns: cols,
      data: someDataInCorrectFormat
  }).draw();
  </code></pre>
  
  <p>The datatable is correctly rendered but it doesn't show the values for the columns where there are some special characters (<code>[</code> and <code>]</code> in my case) in the column names.</p>
  
  <p>Any and all help welcome.</p>
