KeyError: u'\ufeff'

[delta-s-shadow]

Not sure if this is an error on my end, or something I don't understand.

Background:
I'm using a Ukrainian word list to mine tweets from twitter for research. I have it saved as a cPickle file which I upload and able to print into python without any problems.

Problem:
I receive the following error and can't figure out what is going on to is throwing it. Any help would be appreciated.

Traceback (most recent call last):
  File "<pyshell#29>", line 1, in <module>
    execfile("twittersearchloc.py")
  File "twittersearchloc.py", line 25, in <module>
    for tweet in ts.search_tweets_iterable(tso):
  File "C:\Python27\lib\site-packages\twittersearch-1.0.1-py2.7.egg\TwitterSearch\TwitterSearch.py", line 204, in search_tweets_iterable
    self.search_tweets(order)

    self._start_url = order.create_search_url()
  File "C:\Python27\lib\site-packages\twittersearch-1.0.1-py2.7.egg\TwitterSearch\TwitterSearchOrder.py", line 232, in create_search_url
    url += '+'.join([quote_plus(i) for i in self.searchterms])
  File "C:\Python27\lib\urllib.py", line 1310, in quote_plus
    return quote(s, safe)
  File "C:\Python27\lib\urllib.py", line 1303, in quote
    return ''.join(map(quoter, s))
KeyError: u'\ufeff'

How I tried to solve the problem:

I figured the non ascii formart was throwing it off, but trying to decode or encode it into different formats didn't work.

Definitely an encoding error. I guess you are using Python2k, right?

The easiest way would be to use Python3k. Every string in python 3 is unicode by default. So this might actually solve your problem.
