title: Powershell Search String in File Containing $
body: <p>I want to search the following string in a text file: <code>$$u$$</code></p>
  
  <p>I tried <code>select-string</code>, <code>get-content</code>, <code>.Contains</code>. It seems to me it's not possible.</p>
  
  <p>I used this for the search as a variable: <code>$ToSearch = "'$'$u'$'$"</code></p>
  
  <p>It always gives false result.</p>
