Converting Between Unicode Characters and Strings

Unicode is an international standard that aims to represent all known characters used by people in their various languages

public class UnicodeChars {

    public static void main(String[] argv) {

        StringBuffer b = new StringBuffer();
        for (char c = 'a'; c < 'd'; c++) {
            b.append(c);
        }
        b.append('\u00a5');// Japanese Yen symbol
        b.append('\u01FC');// Roman AE with acute accent
        b.append('\u0391');// GREEK Capital Alpha
        b.append('\u03A9');// GREEK Capital Omega
        b.append('\u00E1');// á

        for (int i = 0; i < b.length(); i++) {
            System.out.printf(
                    "Character #%d (%04x) is %c%n",
                    i, (int) b.charAt(i), b.charAt(i));
        }
        System.out.println("Accumulated characters are " + b);
    }
}
//Character #0 (0061) is a
//Character #1 (0062) is b
//Character #2 (0063) is c
//Character #3 (00a5) is ¥
//Character #4 (01fc) is Ǽ
//Character #5 (0391) is Α
//Character #6 (03a9) is Ω
//Character #7 (00e1) is á
