title: COUNTIF not accepting "[x]" anymore
body: <p>It might have been some update I did but since about two months ago, my OpenOffice (4.1.1) does not read <strong>"[x]"</strong> correctly anymore.</p>
  
  <p>I've used it as a substitute of a tickbox in a database but suddenly it started giving me:</p>
  
  <pre><code>=COUNTIF(G2:G589;"[x]")   = 0
  </code></pre>
  
  <p>even though I know for a fact that there's more than 400 entries with that exact string.</p>
  
  <p>Did they change how brackets work somehow?</p>
  
  <p>There's no way the function just has an overflow, right? Because that would be ridiculous.</p>
  
  <hr>
  
  <p>This works just fine though:</p>
  
  <pre><code>=COUNTIF(G2:G589;"-")
  </code></pre>
