Problem with umlauts in checks

[moreamazingnick]

Describe the bug

If you create a check in Icinga director using umlauts for example ü in the parameters the parameter is executed as ü
The services.conf file contains the ü but in the execution the ü is rendered as ü

To Reproduce

1. Use Check command
2. try in powershell: Invoke-IcingaCustomCheck -FileNames "für.txt"
   [OK]
3. Add command using servicetemplate and set parameter
4. icinga renders C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -C "try { Use-Icinga -Minimal; } catch { Write-Output 'The Icinga PowerShell Framework is either not installed on the system or not configured properly. Please check https://icinga.com/docs/windows for further details'; Write-Output "Error: $($_.Exception.Message)Components:rn$( Get-Module -ListAvailable "icinga-powershell-*" )rnModule-Path:rn$($Env:PSModulePath)"; exit 3; }; Exit-IcingaExecutePlugin -Command 'Invoke-IcingaCustomCheck' " -FileNames 'für.txt'
5. and my check cant find the file because the name is wrong.

Expected behavior

render umlauts in command line

I think you have the same problems like we have #8962 - created some days ago ;-)

Dup of #8962.
