How to correctly encode PowerShell script files
Encoding errors occur, when the encoding of your script file does not match the expected encoding of PowerShell. Often encoding errors present themselves as parse errors in scripts.
PowerShell's default encoding varies depending on version.
- In PowerShell 6, 7 or higher, the default encoding is UTF-8 without BOM on all platforms
- In PowerShell 5.1 and below, the default encoding is usually Windows-1252.
It's not possible to force PowerShell to use a specific input encoding. For interoperability reasons, it's best to save scripts in a Unicode format with a BOM.
