How to use additional character encodings in PowerShell Core (Linux) and Desktop (Windows)

Problem

You have to call [System.Text.Encoding]::RegisterProvider([System.Text.CodePagesEncodingProvider]::Instance) when you want to use additional character encodings in PowerShell Core (Linux). On the other hand, calling [System.Text.Encoding]::RegisterProvider([System.Text.CodePagesEncodingProvider]::Instance) causes RuntimeException.

Solution

$PSVersionTable.PSEdition shows current PowerShell edition, so you can switch call [System.Text.Encoding]::RegisterProvider([System.Text.CodePagesEncodingProvider]::Instance) or not.

if ($PSVersionTable.PSEdition -eq "Core") {
  [System.Text.Encoding]::RegisterProvider([System.Text.CodePagesEncodingProvider]::Instance)
}
