Java Utililty Methods UTF16 Convert

String toUTF16LEString(String input)
Convert the input string to String encoded in UTF16LE format.

if (input == null || input.length() == 0) {
 return input;
byte[] b = input.getBytes("UTF-16LE");
return hexToString(b);

int UTF16toUTF8(CharSequence s, int offset, int len, byte[] result, int resultOffset)
Writes UTF8 into the byte array, starting at offset.

final int end = offset + len;
int upto = resultOffset;
for (int i = offset; i < end; i++) {
 final int code = (int) s.charAt(i);
 if (code < 0x80)
 result[upto++] = (byte) code;
 else if (code < 0x800) {
 result[upto++] = (byte) (0xC0 | (code >> 6));
