How to handle unicode chars in Java

Question

I have been trying to achieve the following :

I want to be able to paste a string of Unicode characters ex : 🖕🏼🙅🏽 without java showing them as being unrecognized. How do I make a Java JTextPane able to handle Unicode characters?

Answer 1

If you want to use Unicode character you have to write it like this: \u[unicode]. So for example:

 JOptionPane.showMessageDialog(null, "\u2764Guess number", "game", JOptionPane.INFORMATION_MESSAGE);

would produce the folowing: ❤Guess number. I hope I answered your question.
