title: Regular expression: how to capture word with only one repeated symbol
body: <p>Having an input of</p>
  
  <pre><code>aaadds bbbbb/bbbbb asdfdasf cccccccccc  \n
  fffffff
  </code></pre>
  
  <p>What is the correct regex for getting <code>cccccccccc</code> and <code>fffffff</code>?</p>
  
  <p>It should be something like <code>[.]+</code> except for the fact that dot inside the square brackets is literal and one can't simply backslash it.</p>
  
  <p>UPD: also this should work for
  aaadds bbbbb/bbbbb asdfdasf cccccccccc  \n s """""
      fffffff
  adding c and """"" to the result.
  thanks arshajii for the correct answer</p>
