powershell fehlt der Terminator: "

Ich habe den folgenden Skriptcode

    #[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'

Ich führe das Skript aus mit:.\Deployrelease.ps1 -ReleaseFile ".\Deploy.Zip" -Destination "."

Aber ich bekomme das immer wieder:

    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

Ich konnte den Fix nicht finden, da ich kein Problem sehe.

Irgendeine Hilfe?
