String hexCode = Integer.toHexString(str_code.codePointAt(0)).toUpperCase();        
    String hexCodeWithAllLeadingZeros = "0000" + hexCode;
    String hexCodeWithLeadingZeros = hexCodeWithAllLeadingZeros
    .substring(hexCodeWithAllLeadingZeros.length() - 4);
    hexCodeWithLeadingZeros = "\\u" + hexCodeWithLeadingZeros;
    System.out.println("Unicode " + hexCodeWithLeadingZeros);
    return hexCodeWithLeadingZeros;
}
