PEP: 0263 Title: 	Defining Python Source Code Encodings

I tried using the bare module and I got the following  error 
![err](https://cloud.githubusercontent.com/assets/4489002/4492790/2ca48558-4a44-11e4-96a7-fa4f6658e52d.png)

I understand this is a module and there is no need for the encoding at the top is someone is going to use it by importing the functions.
But for the purpose of helping anyone who might get similar err while using the module, I've included a defined code encoding to utf-8. 

The encoding doesn't affect the code, I've tested it and I'm still using that encoding.
