codec error in winrm-exec.py 'utf-8' codec can't encode characters

[EddyKIL]

Hi,
I'm getting the following error, when running job using py-winrm:

'utf-8' codec can't encode characters in position 4903-4904: surrogates not allowed (winrm-exec.py:339)[root]
My job is a simple listing of user directory: dir

Python version: 3.6
Windows nodes: Win Server 2016 Datacenter
py-winrm: 2.1.1

Hello. I have the same exact issue. When executing a python script locally, it works fine. When executing through rundeck using WinRMPython, I get the error message:

[ERROR ] 'utf-8' codec can't encode characters in position 2329-2330: surrogates not allowed (winrm-exec.py:379)[root]

I'm also not outputting any complicated log. Just 3 lines of information. I get the error when using logging module or a basic print.

Similar error '[ERROR ] 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte (winrm-exec.py:316)[root]'

Is reliably replicated by attempting to run handle.exe using Rundeck.
