title: str_word_count and Arabic text
body: <p>I used the function str_word_count to count how many ARABIC words are in a text, but it returns zero:</p>
  
  <pre><code>$sentence = 'بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ';
  $countSentence = str_word_count($sentence);
  echo 'Total words '.$countSentence.'&lt;br /&gt;';
  </code></pre>
  
  <p>Thanks in advance</p>
