Because PowerShell return not valid UTF-8

FYI: This behavior is not limited to PowerShell, using Command Prompt has the same issue if I remember correctly.

As the default output encoding on Windows is system locale dependent, It seems that we should either use PackedByteArray instead of String, or find a way to retrieve the "Unicode" output.

PackedByteArray won't help, Windows console output default to ASCII, so it's not sending full characters through the pipe.
Normally, encoding can be set be the shell (using chcp command) or app that's writing to the console SetConsoleOutputCP, but seems like it can't be set by the parent process.
