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 o

Answer 1

System.out uses the default encoding of the underlying operating system which typically is ISO-8859-1 or UTF-8. The first is what I have with the 1252 codepage under XP.

Is this in a CMD.EXE window, or inside an IDE?
