title: Ignore '️' while tokenizing tweets
body: <p>I'm making a twitter web crawler for sentiment analysis. 
  I'm following this tutorial <a href="https://marcobonzanini.com/2015/03/23/mining-twitter-data-with-python-part-4-rugby-and-term-co-occurrences/" rel="nofollow noreferrer">https://marcobonzanini.com/2015/03/23/mining-twitter-data-with-python-part-4-rugby-and-term-co-occurrences/</a>.</p>
  
  <p>In this tutorial(part 3) Marco teaches how to ignore some terms using a stop variable in his algorithm. However when I start to collect the tweets and try to match the co-occurrence matrix - which contains the number of times the term x has been seen in the same tweet as the term y - tweepy is collecting this term: <code>'️'</code> . I don't know what this is in Unicode and how can I ignore. </p>
  
  <p>I've tried the apostrophe, single right/left quote, and none of these seems to work.</p>
  
  <p>Any thoughts?</p>
