title: Remove duplicated strings within Notepad++
body: <p>I was trying to find a way to remove duplicated strings within Notepad++ (not removing duplicated lines). For example, if I have the text:</p>
  
  <p>Alice's favorite ice cream (not gelato) is: Vanilla! Alice's favorite ice cream (not gelato) is: Vanilla! Please go get some ice cream from the store</p>
  
  <p>The result should be</p>
  
  <p>Alice's favorite ice cream (not gelato) is: Vanilla! Please go get some ice cream from the store</p>
  
  <p>I tried looking up some examples and found <a href="https://stackoverflow.com/questions/14302308/removing-duplicate-strings-wordsnot-lines-using-regexnotepad">this</a> but it doesn't really work exactly as expected. Thanks in advance.</p>
