The settings are not configured correctly, make sure that the your File encodings are set to UTF-8, in particular the 'Default encoding properties files'. On my side the steps below didnt work until I changed the default encoding.

On Intellij 2017.3.1 (Community Edition) File | Settings | Editor > File Encodings . Click on link below to see settings image
