title: Finding files ISO-8859-1 encoded?
body: <p>I have a bunch of files with a mixtures of encodings mainly ISO-8859-1 and UTF-8.</p>
  
  <p>I would like to make all files UTF-8, but when trying to batch encode this files using
  iconv some problems arise. (Files cuts by half, etc.)</p>
  
  <p>I supposse the reason is that iconv requires to know the 'from' encoding, so if the command looks like this</p>
  
  <pre><code>iconv -f ISO-8859-1 -t UTF-8 in.php -o out.php
  </code></pre>
  
  <p>but 'in.php' if already UTF-8 encoded, that causes problems (correct me if I'm wrong)</p>
  
  <p>Is there a way, that I can list all the files whose encoding is not UTF-8?</p>
