New-PSsession not working in Script - powershell

Question

I have a strange problem with one of my servers :
I am trying to open a PSsession with it.
If I copy my script directly in powershell everything works fine, but if i run it via a .ps1 file I get a access denied error.
The same sript works on multiple machines except this one.
Additonal information:
Executing Server : Server 2012
Target Server2003SP2
Another Server2003SP2 is working fine without a Problem
the Client Server was configured using :
Enable-PSRemoting -Force
Set-Item wsman:\localhost\client\trustedhosts MY2012Server -concatenate -force
Restart-Service WinRM
And the Error Message:
New-PSSession : [Server2003SP2] Connecting to remote server Server2003SP2 failed with the following error message : Access is denied. For more information,
Help topic.

Edit : My full SCript as requested :
$Password = "Hereismypasswordwith#and€init"
$Username = "Servername\Administrator"
$Servername = "Servername"
$Language = {
$oscode = Get-WmiObject Win32_OperatingSystem -ErrorAction continue
$oscode = $oscode.oslanguage
$switch = switch ($oscode){
1031 {"Deutsch"};
1033 {"English"};
default {"English"};
}
write-host $switch
return $switch
}
$SecurePassWord = ConvertTo-SecureString -AsPlainText $Password -Force
$Cred = New-Object -TypeName "System.Management.Automation.PSCredential" -ArgumentList $Username, $SecurePassWord
$pssessionoption = new-pssessionoption -operationtimeout 7200000 -IdleTimeout 7200000
$Session = New-PSSession -ComputerName $Servername -credential $Cred -sessionOption $pssessionoption
Invoke-Command -Session $Session -Scriptblock $Language
Remove-PSSession -Session $Session
UPDATE :
it seems to be something within the Char encoding.
the password in the ps1 file produces a difrent output for the € in it :
in the ps1. ¬
in the ps window : ?
if i pass the Password as a Paramter it also works.
$password.gethash() also prouces difrent outputs. codepage is the same though (chcp)
the script was created in notepad++
