title: writing double quotes to file name text with powershell
body: <p>I have been at great pains to see where I've gone wrong here in adding double quotes to file name text. The following code works fine under the -whatif umbrella but not without.</p>
  
  <pre><code>$a = "20`" board"
  get-childitem | rename-item -newname {$_.fullname -replace "20 board", $a } -whatif
  
  get-childitem | rename-item -newname {$_.fullname -replace "20 board","20`" board" } -whatif
  </code></pre>
  
  <p>The desired outcome is to replace <code>20 board</code> with <code>20" board</code>.
  The above snippets give me a <code>rename-item : Illegal characters in path.</code> error.</p>
