title: Convert integer array to string at javascript
body: <p>Here is php code:</p>
  
  <pre><code>$arr=array(228,184,173,230,150,135,99,104,105,110,101,115,101);
  $str='';
  foreach ($arr as $i){
      $str.=chr($i);
  }
  print $str;
  </code></pre>
  
  <p>the output is: <code>中文chinese</code></p>
  
  <p>Here is javascript code:</p>
  
  <pre><code>var arr=[228,184,173,230,150,135,99,104,105,110,101,115,101];
  var str='';
  for (i in arr){
      str+=String.fromCharCode(arr[i]);
  }
  console.log(str);
  </code></pre>
  
  <p>the output is: <code>ä¸­æchinese</code></p>
  
  <p>So how should I process the array at javascript?</p>
