title: Python regex not matching
body: <p>I am trying to extract a file name using regex. File names are in the list <code>files</code> , the pattern to be matched is <code>songTitle</code>. </p>
  
  <pre><code> files = listdir(curdir)
          print("Pattern : %s" % songTitle)
          for songs in files:
              print(songs)
              re_found = re.match(re.escape(songTitle) + r'.*\.mp3$', songs)
              if re_found:
                  FileName = re_found.group()
                  print(FileName)
                  break
  </code></pre>
  
  <p>In this example </p>
  
  <p><code>files</code> contains :</p>
  
  <pre><code>['.DS_Store', '__init__.py', 'command_line.py', "Skrillex &amp; Diplo - 'Mind' feat. Kai (Official Video)-fDrTbLXHKu8.mp3"]
  </code></pre>
  
  <p><code>songTitle</code> (Pattern to be matched) : <code>Skrillex &amp; Diplo - 'Mind' feat. Kai (Official Video)</code></p>
  
  <p>Output : </p>
  
  <pre><code>Pattern : Jack Ü - Take Ü There feat. Kiesza [OFFICIAL VIDEO]
  .DS_Store
  __init__.py
  command_line.py
  Jack Ü - Take Ü There feat. Kiesza [OFFICIAL VIDEO]-C9slkeFXogU.mp3
  Skrillex &amp; Diplo - 'Mind' feat. Kai (Official Video)-fDrTbLXHKu8.mp3
  </code></pre>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I ran some tests and realised that the problem occurs due to non ascii characters. Such as the 'Ü' in this case.</p>
