Java Utililty Methods Unicode to String

String Unicode2Str(String s)
Unicode Str

int i = 0;
int len = s.length();
StringBuffer sb = new StringBuffer(len);
while (i < len) {
 String t = s.substring(i, i + 4);
 char c = (char) Integer.parseInt(t, 16);
 i += 4;
 sb.append(c);
...

String unicode2String(String unicodeStr)
unicode String

StringBuffer sb = new StringBuffer();
String[] str = unicodeStr.toUpperCase().split("\\\\U");
for (int i = 0; i < str.length; ++i)
 if (!str[i].equals("")) {
 char c = (char) Integer.parseInt(str[i].trim(), 16);
 sb.append(c);
return sb.toString();
...

String unicodeStringToPrettyString(String s)
Returns the most succinct possible, human-readable, ASCII form of the String s of Unicode codepoints.

if (s == null)
 return "null";
StringBuffer sb = new StringBuffer(s.length() * 6);
for (int i = 0; i < s.length(); i++) {
 sb.append(unicodeCodepointToString(s.charAt(i), true));
return sb.toString();

void unicodeToAscii(String name, StringBuffer result)
unicode To Ascii

for (int i = 0; i < name.length(); i++) {
 if (Character.isLetterOrDigit(name.codePointAt(i)) || Character.isSpaceChar(name.codePointAt(i))
 || name.charAt(i) == '_' || name.charAt(i) == '$') {
 result.append(name.charAt(i));
 } else {
 result.append("U+" + Integer.toHexString(name.codePointAt(i)).toUpperCase());

String unicodeToAscii(String theString)
unicode To Ascii

char aChar;
int len = theString.length();
StringBuffer outBuffer = new StringBuffer(len * 2);
for (int x = 0; x < len;) {
 aChar = theString.charAt(x++);
 switch (aChar) {
 case '\\':
 outBuffer.append('\\');
...

String unicodeToString(int unicode)
unicode To String

switch (unicode) {
case 0x00:
 return "\0円";
case 0x08:
 return "\\b";
case 0x09:
 return "\\t";

String unicodeToString(String escaped)
unicode To String

int len = escaped.length();
StringBuffer buf = new StringBuffer();
int value = 0;
for (int x = 0; x < len;) {
 int c = escaped.charAt(x++);
 if (c == 92) {
 c = escaped.charAt(x++);
 if (c == 117) {

unicode To String

int t = hex.length() / 6;
int iTmp = 0;
StringBuilder str = new StringBuilder();
for (int i = 0; i < t; i++) {
 String s = hex.substring(i * 6, (i + 1) * 6);
 iTmp = Integer.valueOf(s.substring(2, 4), 16).intValue() << 8
 | Integer.valueOf(s.substring(4), 16).intValue();
 str.append(new String(Character.toChars(iTmp)));
...

String unicodeToString(String unicodeStr)
unicode To String

StringBuffer sb = new StringBuffer();
String[] str = unicodeStr.toUpperCase().split("\\\\U");
for (int i = 0; i < str.length; i++)
 if (!str[i].equals("")) {
 char c = (char) Integer.parseInt(str[i].trim(), 16);
