title: What's an OSX command line tool or simple app to remove extended ASCII characters from source text files?
body: <p>I've been cutting and pasting some code snippets from an Amazon Kindle eBook into a text editor (JetBrains PhpStorm), and apparently each time it comes with some extended (>127) ASCII characters.</p>
  
  <p>Is there simple cmd line sed/awk/tr command, or a simple OSX App to strip them out?</p>
