Unicode characters appear as question marks in IntelliJ IDEA console

Question

I'm trying to write Unicode characters (♠) using System.out, and a question mark (?) gets printed instead.

How can I have proper Unicode characters displayed instead of question marks?

I'm using IntelliJ IDEA on Windows, and trying to print from within the IDE.

Answer 1

Is the file encoding configured correctly? See that "Settings | File Encodings" uses UTF-8. Printing ♠ works for me when I have IDE encoding and all files set to UTF-8. Recompiling may be needed after changing the encoding.
