They aren't done by String literals.

Exactly how?

No.

That's not exactly correct, and it certainly is not the same part that translates '\t'.

Nope.

You want to do what, exactly? I'm not clear on what you're trying to accomplish.

'\u' sequences are pre-compile, not during compile. Their presence is exactly equivalent 
to typing the corresponding Unicode character directly. 

You can embed them in identifiers, directives, anywhere the corresponding character can go.

Not just literals.

For that matter, you can use them in numeric literals.

     * @param args String array of arguments.
     */
    public static void main(String[] args) {
        System.out.println("COUNT = \u0022+ COUNT);
    }
}
