 Sorry, this version of ftfy is no longer written for Python 2.
 
-It is much easier to provide consistent handling of Unicode when developing
-only for Python 3. ftfy is exactly the kind of library that Python 3 is
-designed for, and now there is enough Python 3 usage that we can take advantage
-of it and write better, simpler code.

 The older version of ftfy, version 4.4, is still available and can run on
 Python 2. Try this:
 
     pip install ftfy==4.4.3
