Java Utililty Methods Unicode Create

byte[] getUnicodeByteArray(String str)
get Unicode Byte Array

ByteArrayOutputStream baos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(baos);
try {
 for (int i = 0; i < str.length(); i++) {
 dos.writeChar((int) str.charAt(i));
} catch (Exception e) {
return baos.toByteArray();

byte[] getUnicodeBytes(String s)
Converts the string into a little-endian array of Unicode bytes

try {
 byte[] b = s.getBytes(UNICODE_ENCODING);
 if (b.length == (s.length() * 2 + 2)) {
 byte[] b2 = new byte[b.length - 2];
 System.arraycopy(b, 2, b2, 0, b2.length);
 b = b2;
 return b;
...

String getUnicodeString(byte bytes[], int offset, int len)
Get UNICODE String.

try {
 return new String(bytes, offset, len * 2, UNICODE_ENCODING);
} catch (UnsupportedEncodingException e) {
 return "";

String getUnicodeString(byte[] d, int length, int pos)
Gets a string from the data array

try {
 byte[] b = new byte[length * 2];
 System.arraycopy(d, pos, b, 0, length * 2);
 return new String(b, UNICODE_ENCODING);
} catch (UnsupportedEncodingException e) {
 return "";

String getUnicodeText(Object text)
get Unicode Text

if (text == null) {
 return null;
} else if (text instanceof byte[]) {
 return new String((byte[]) text, "UTF-8");
} else {
 return String.valueOf(text);

String toUnicode(char c)
to Unicode

return toUnicode(String.valueOf(c));

String toUnicode(final String toUnicode, final boolean toLowerCase)
Converts all characters from the given String to unicodes characters encoded like \uxxxx.

final StringBuilder sb = new StringBuilder();
for (int i = 0; i < toUnicode.length(); i++) {
 final String hex = Integer.toHexString(toUnicode.codePointAt(i));
 if (toLowerCase) {
 hex.toLowerCase();
 } else {
 hex.toUpperCase();
 final String hexWithZeros = "0000" + hex;
 final String hexCodeWithLeadingZeros = hexWithZeros.substring(hexWithZeros.length() - 4);
 sb.append("\\u" + hexCodeWithLeadingZeros);
return sb.toString();

String toUnicode(String input)
to Unicode

StringBuilder ret = new StringBuilder();
for (int i = 0; i < input.length(); i++) {
 char ch = input.charAt(i);
 if (!Character.isWhitespace(ch) && ch < 0x20 || ch > 0x7e) {
 ret.append("\\u");
 ret.append(leading4Zeros(Integer.toHexString(ch)));
 } else {
 ret.append(ch);

String toUnicode(String input)
to Unicode

String output = "";
try {
 if (input != null && input.length() > 0) {
 for (int i = 0; i < input.length(); i++) {
 output += toUnicode(input.charAt(i));
} catch (Exception e) {

String toUnicode(String input)
to Unicode

StringBuffer ret = new StringBuffer();
