How to use Special Chars in Java/Eclipse

Question

How can I use/display characters like ♥, ♦, ♣, or ♠ in Java/Eclipse?

When I try to use them directly, e.g. in the source code, Eclipse cannot save the file.

Either change your encoding to one which will cope, e.g. UTF-8, or find the relevant Unicode number and use a \uxxxx escape sequence to represent it.
