You’re not escaping your double-quotes properly. To escape double quotes, either use a pair of double-quotes or use the backtick character. For example:
“”"Hello”"” # Outputs: “Hello”
“`"Hello`”" # Outputs: “Hello”
In contrast, using backslashes like you are will just generate an error because PowerShell doesn’t treat those as escaped double-quotes:
PS C:\> “\”Hello\”"
At line:1 char:4
+ “\”Hello\”"
+ ~~~~~~~~
Unexpected token ‘Hello\”"‘ in expression or statement.
