title: Issue: Decoding a file on linux machine from command line
body: <p>I have some French codepoints that i would like to decode to utf-8 on a Linux System.
  The content of my file is (little example):<br></p>
  
  <p><code>Lemari%C3%A9%20</code><br></p>
  
  <p>Which decoded should be: <code>Lemarié</code></p>
  
  <p>I read that iconv is a great tool for achieving this but i dont know what i should use as <code>-f</code> argument, because the file content is encoded, so  am only trying with the <code>-t</code> option without success:
  <code>iconv -t UTF8 test.csv</code></p>
  
  <p>Any advice?</p>
