a Powershell le falta el terminador: "

Tengo el siguiente código de script

    #[string]$password = $( Read-Host "Input password, please" )
    param (
        [string]$ReleaseFile = $(throw "-ReleaseFile is required"),
        [string]$Destination = $(throw "-Destination is required")
    )

    function unzipRelease($src, $dst)
    {
        $shell = new-object -com shell.application
        $zip = $shell.NameSpace($src)
        foreach($item in $zip.items())
        {
            $shell.Namespace($dst).copyhere($item)
        }
    }

    #  .\deployrelease.ps1 -ReleaseFile ".\deploy.zip" -Destination "."

    unzipRelease –Src '$ReleaseFile' -Dst '$Destination'

Corro el script con: .\deployrelease.ps1-ReleaseFile ".\desplegar.zip "- Destino"."

Pero sigo recibiendo esto:

    PS C:\Users\Administrator\Documents\Tools> .\deployrelease.ps1 -ReleaseFile ".\deploy.zip" -Destination
    The string starting:
    At C:\Users\Administrator\Documents\Tools\deployrelease.ps1:19 char:16
    + unzipRelease â? <<<< "Src '$ReleaseFile' -Dst '$Destination'
    is missing the terminator: ".
    At C:\Users\Administrator\Documents\Tools\deployrelease.ps1:19 char:55
    + unzipRelease â?"Src '$ReleaseFile' -Dst '$Destination' <<<<
        + CategoryInfo          : ParserError: (Src `'$ReleaseF...'$Destination`':String) [], ParseException
        + FullyQualifiedErrorId : TerminatorExpectedAtEndOfString

No pude encontrar la solución ya que no veo ningún problema.

Alguna ayuda?
