Just had a powershell script that was failing

When I went in to the registry key that stores the results of the script running I saw some corrupted characters

The problem turned out to be I had a file that was encoded in UTF-16LE

So I saved the powershell script as UTF-8 and then deleted the current script and re-uploaded and it worked fine

Write-Host “Running Remove Mail App”
Get-AppxPackage Microsoft.windowscommunicationsapps | Remove-AppxPackage
Write-Host “End Remove Mail App”

And another thing
