title: .loc cannot find elements in a dataframe
body: <p>I have a 6x2 dataframe called 'MyDataFrame'. Here is how it looks:</p>
  <p><a href="https://i.stack.imgur.com/pD1DE.jpg" rel="nofollow noreferrer">MyDataFrame</a></p>
  <p>Its first column is called 'Keyword' and 2nd column is called 'Word'. I use the code below to find the row that contains a specific word in the 'Word' column.</p>
  <p>Interestingly, the code works when I search for the word 'Aal' however it does not work for 'Aachenerin'</p>
  <p>DOES NOT WORK</p>
  <p><code>List_of_Keywords = MyDataFrame.loc[MyDataFrame['Word'] == &quot;Aachenerin&quot;]</code></p>
  <p>WORKS</p>
  <p><code>List_of_Keywords = MyDataFrame.loc[MyDataFrame['Word'] == &quot;Aal&quot;]</code></p>
  <p>Any suggestions about why it is not working for 'Aachenerin'?</p>
  <p>I also noticed something weird. When I copy the expression 'Aachenerin' from MyDataFrame and paste it into an Excel file, it pastes as 'Aa-che-ne-rin'. I have no idea where the dashes are coming from. Maybe the problem is about this.</p>
  <p>Thank you so much for your responses in advance.</p>
