title: Regex - Check a bracket/parenthese is not closed (including nested)
body: <p>I would like to have a match when a bracket/parenthese is not closed, or if one is closed but not opened, including nested (using notepad++ regex search).</p>
  
  <p>For example :</p>
  
  <p><code>[Text]</code> (ok)</p>
  
  <p><code>[Text</code> (not ok)</p>
  
  <p><code>Text]</code> (not ok)</p>
  
  <p><code>[Text (test]</code> (not ok)</p>
  
  <p><code>[Text test)]</code> (not ok)</p>
  
  <p><code>[Text (test)]</code> (ok)</p>
  
  <p>It could be nice if I can do the same with the { and }.</p>
