console: Failed to install '': java.nio.charset.UnsupportedCharsetException: cp65001.

See original GitHub issue

It seems -Dpython.console.encoding=UTF-8 as a VM argument can solve the issue, as described here: https://stackoverflow.com/questions/30443537/how-do-i-fix-unsupportedcharsetexception-in-eclipse-kepler-luna-with-jython-pyde

However, I cannot find where to add that one to in Processing.

Installed Python mode from “Add Mode” Wrote a test code and run

def setup():
    size(800, 480)

def draw():
    background(0)

Error message was console: Failed to install ‘’: java.nio.charset.UnsupportedCharsetException: cp0.

Edit: Was using Processing 3.4. Problem no longer persists in Processing 3.5.3.

On my PDE 3.4 install, I cannot reproduce this error with PythonMode 3041 installed.

However, on PDE 3.4, when I try to update to PythonMode 3056 via Contributions Manager, it downloads, archives the old Mode in Libraries/old, and then errors out with the dialog message “Error during download and install of Python Mode for Processing 3.” So possibly some mode/PDE incompatibilities, and using the latest of each is a fix.
