Code is not working on an mac OSX with python 2.7.12
<p>I want to use this code for my data distribution, but I can't save the file or when I run this in python directly I got this error:</p>

<blockquote>
  <p>Unsupported characters in input</p>

<p>I think this code is generated on a windows environment and this is not working for macOSX. I installed all necessary packages.</p>
