 How can I manage this type of special character in PowerShell?   
 
 
 Has found a great explanation for the exact cause of your problem, but it is a very simple solution.  The operator uses regular expressions that need to be avoided, but .

  Dir | rename-item -newname {$ _. Name.Replace ("(", ""}}
