title: move_uploaded_file does not support utf8 file name
body: <p>I am using <a href="http://www.uploadify.com/" rel="nofollow noreferrer">uploadify</a> and the file name retrieved from $_FILES["fileData"]["name"] on server side is in utf8. It may contain chinese or japanese characters. After the following codes run,</p>
  
  <pre><code>$tempFileWithPath = $_FILES['Filedata']['tmp_name'];
  $destFile = $_FILES['Filedata']['name'];
  
  $destFileWithPath=myUtility::getFileRepositoryPath().'/'.$destFile;
  move_uploaded_file($tempFileWithPath,$destFileWithPath);
  </code></pre>
  
  <p>For those files using chinese or japanese file name, I used filezilla ftp client (which supports utf8 file name) and browser the folder and found that they all become ?????. Of course, other files using english-only file name do not have this problem.</p>
  
  <p>I am using php 5.2.9 and the server is linux on a shared hosting.</p>
  
  <p>Is it true that all file-related functions in PHP have problems supporting utf8? Or my problem is related to other issues?</p>
