File was loaded in the wrong encoding:'UTF-8' in IntelliJ IDEA

Question

Before asking the question, I searched for a similar question on StackOverflow:

file was loaded in the wrong encoding: 'UTF-8' in android studio

But

Answer 1

My colleague works on Windows while I work on Ubuntu 16.04

Click the Reload in another encoding, and click the more -> GBK.

Then we can see the Chinese character.
