title: Convert files encoding
body: <p>I have a PHP application who's files encoding is Greek ISO (iso-8859-7). I want to convert the files to utf-8 but simply saving the files with utf-8 isn't enough since the Greek texts get garbled. Is there an "automatic" method to do this so that I can completely convert my app's encoding without having to go through each file and rewrite the texts?</p>
