unicode

if (ipStr == null)
 return ipStr;
switch (ipStr) {
case "\\u0001":
 return "\u0001";
case "\\u0002":
 return "\u0002";

String unicode(String s)
unicode

final StringBuilder result = new StringBuilder();

 if (c > 127 || c == '&' || c == '|') {
 final int i = c;
 result.append("&#" + i + ";");
 } else {
 result.append(c);

void unicode(StringBuilder buf, char c)
Represent as unicode

buf.append("\\u");
int n = c;
for (int i = 0; i < 4; ++i) {
 int digit = (n & 0xf000) >> 12;
 buf.append(hex[digit]);

String Unicode2ASCII(String unicode)
Creates a new instance of ThaiUtil

StringBuffer ascii = new StringBuffer(unicode);
int code;
for (int i = 0; i < unicode.length(); i++) {
 code = (int) unicode.charAt(i);
 if ((0xE01 <= code) && (code <= 0xE5B)) {
 ascii.setCharAt(i, (char) (code - 0xD60));

byte[] unicode2Byte(String s)
unicode Byte

int len = s.length();
byte abyte[] = new byte[len << 1];
int j = 0;
for (int i = 0; i < len; i++) {
 char c = s.charAt(i);
 abyte[j++] = (byte) (c & 0xff);
 abyte[j++] = (byte) (c >> 8);

String Unicode2GBK(String dataStr)
Unicode GBK

int index = 0;
StringBuffer buffer = new StringBuffer();
int li_len = dataStr.length();
while (index < li_len) {
 if (index >= li_len - 1 || !"\\u".equals(dataStr.substring(index, index + 2))) {

char unicodeChar(char a, char b, char c, char d)
unicode Char

return (char) ((c2i(a) << 12) + (c2i(b) << 8) + (c2i(c) << 4) + c2i(d));

String unicodeCodepointToString(char cp, boolean shortenIfPossible, String prefix, boolean upperCase)
Like #unicodeCodepointToString(char,boolean) if you pass in "\\u" as prefix.

if (shortenIfPossible) {
 if ((cp >= 'a' && cp <= 'z') || (cp >= 'A' && cp <= 'Z') || (cp >= '0' && cp <= '9') || cp == '\\'
 || cp == '~' || cp == '`' || cp == '.' || cp == ',' || cp == ' ' || cp == '\'' || cp == '"'
 || cp == '+' || cp == '-' || cp == '=' || cp == '_' || cp == '@' || cp == '!' || cp == '#'
 || cp == '$' || cp == '%' || cp == '^' || cp == '&' || cp == '*' || cp == ':' || cp == '['
 || cp == ']' || cp == '(' || cp == ')' || cp == '{' || cp == '}')
 return new String(new char[] { cp });
 if ('\t' == cp)

char[] out = new char[len];
int outLen = 0;
while (off < len) {
