When using python3-function node, I'm always seeing the error below when running any code. For testing purposes, I just used the line "print("test")" in my python3-function node. [Anotação 2020-03-03 154440] I'd like to know if anyone has dealed with this issue and how to solve it.

I'm running it in a Pi3, works fine there, check that you have the latest Python3 node installed [image]

It might be, once again, for running it on Windows. Python and encoding is always iffy, it's my biggest complaint I have on the language. Windows is not the best either when it comes to this, sadly.
