title: Should we sanitize file names uploaded to server?
body: <p>When uploading files to a server. Should the file name be sanitized? i.e. avoiding non-ASCII characters like <code>é</code> or <code>&amp;</code>?</p>
  
  <p>Or should we allow these files to be saved as is?</p>
  
  <p>PS. In Rails 3, I can't remember the method. It changes non-ascii chars to underscores and etc. Someone remind me pls. It's not <code>sanitize</code>. Its a different method.</p>
