title: Using preg_replace/str_replace for json data
body: <p>I am getting data from a json array which contains the special character "Â " which I'd like to remove. </p>
  
  <pre><code>$jsonString = preg_replace("#Â+\s#", "", $jsonString);
  $jsonString = preg_replace("#&lt;p&gt;Â.*&lt;/p&gt;#", "", $jsonString);
  $jsonString = str_replace("Â&amp;nbsp;", "", $jsonString);
  </code></pre>
  
  <p>The above lines are some of the code I've tried using to no avail. So the first question in mind is, is it even possible to use str_replace or preg_replace in json data? If not, is there any other function I can use to remove the specified special character from the string?</p>
