How do I make IDLE use UTF-8 as the default encoding for my Python files ?
There is no "Encoding" option in IDLE settings.
1) Navigate to the folder with your current version of python. Mine is:
/System/Library/Frameworks/Python.framework/Versions/2.7/Resources
2) View the python application package, as this is the IDLE.
3) You should see a file called Info.plist containing the line-
<?xml version="1.0" encoding="UTF-8"?>
4) Here you can modify the encoding, keep in mind python dose not support all source encoding options.
Configure IDLE to use Unicode
