encoding

When running the script extract below it used different encoding when running from command shell or as scheduled task!

The relevant command is 'Add-Content', why does it be have different when running this directly wihtin a command window then running as scheduled task. Why do they use different encoding (which messes up the logfile).

# Function to print-out messages, including <date> and <time> information.
$scriptName = $MyInvocation.MyCommand.Name
$logFile = "$env:ProgramData\Siemens\LMS\Logs\CleanUp.log"  
function Log-Message
{
    [CmdletBinding()]
    Param
    (
        [Parameter(Mandatory=$true, Position=0)]
        [string]$LogMessage
    )

	$logEntry = "[$scriptName/$scriptVersion] $(Get-Date -Format 'yyyy-MM-dd HH:mm:ss') - $LogMessage"  
    Write-Output $logEntry
	Add-Content -Path $logFile -Value $logEntry -Encoding ASCII 
}

What I have tried:

Tried with and without '-Encoding ASCII'
