Answer 1

For PowerShell 5.1, enable this setting:

Control Panel, Region, Administrative, Change system locale, Use Unicode UTF-8 for worldwide language support

Then enter this into PowerShell:

$PSDefaultParameterValues['*:Encoding'] = 'Default'

Alternatively, you can upgrade to PowerShell 6 or higher.
