Heroku pip problem

I had a problem with deploying one very simple app to Heroku. Here is the error:

-----> Installing dependencies using Pip (1.3.1)
           Exception:
           Traceback (most recent call last):
             File "/app/.heroku/python/lib/python2.7/site-packages/pip-1.3.1-py2.7.egg/pip/basecommand.py", line 139, in mai

               status = self.run(options, args)

               req = InstallRequirement.from_line(line, comes_from)
             File "/app/.heroku/python/lib/python2.7/site-packages/pip-1.3.1-py2.7.egg/pip/req.py", line 96, in from_line

               st = os.stat(s)
           TypeError: must be encoded string without NULL bytes, not str

           Storing complete log in /app/.pip/pip.log

     !     Push rejected, failed to compile Python app

Since there is no access to files on Heroku (they are overridden). I fired pip on my local machine to see the log:

C:\Python27\Scripts\pip-script.py run on 10/12/13 02:48:15
Exception:

    reqs = list(parse_requirements(s))
  File "C:\Python27\lib\site-packages\pkg_resources.py", line 2424, in parse_requirements
    raise ValueError("Missing distribution spec", line)
ValueError: ('Missing distribution spec', '\xff\xfeF\x00l\x00a\x00s\x00k\x00=\x00=\x000\x00.\x001\x000\x00.\x001\x00')

seems my requirements.txt file was encoded as UTF and pip wasn't happy about it. Converting to ASCII solves the problem.

Say Thanks

There are dozens ways! you can just open it in Notepad++ and change encoding in menu or you can google how to do it :)
