PowerShell is missing the terminator: "

I have the following script code

#[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'

I run the script with: .\deployrelease.ps1 -ReleaseFile ".\deploy.zip" -Destination "."

But I keep getting this:

PS C:\Users\Administrator\Documents\Tools> .\deployrelease.ps1 -ReleaseFile ".\deploy.zip" -DestinationThe 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

I couldn't find the fix as I do not see any problem.

Any help?
