title: How to deal with variations in apostrophe ’ and '
body: <p>I am doing an NLP processing and I have tweets with text as I’ll instead of I'll. Same is the case with quotation marks: “God please save us” instead of "God please save us"</p>
  
  <p>My approach in pandas series:</p>
  
  <pre><code>tweets.str.replace(r"’", "'")
  </code></pre>
  
  <p>I expect other variations. What is the industry approach to standardizing? Many thanks.</p>
