How to get unicode characters from String ?

Below is the Example.....

StringBuffer a = new StringBuffer();
try {
String line = "Shailesh Shukla";
for (int index = 0; index < line.length(); index++) {
String hexCode = Integer.toHexString(line.codePointAt(index))
.toUpperCase();
String hexCodeWithAllLeadingZeros = "0000" + hexCode;
String hexCodeWithLeadingZeros = hexCodeWithAllLeadingZeros
.substring(hexCodeWithAllLeadingZeros.length() - 4);
a.append("\\u" + hexCodeWithLeadingZeros + " ");
}
} catch (Exception e) {
}
System.out.println(a.toString());
