Some code from my shelf:
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Unescape {
private static final Pattern p = Pattern.compile("\\\\u([0-9A-F]{4})");
public static String U2U(String s) {
String res = s;
Matcher m = p.matcher(res);
while(m.find()) {
res = res.replaceAll("\\" + m.group(0),
Character.toString((char)Integer.parseInt(m.group(1), 16)));
}
return res;
}
public static void main(String[] args) {
System.out.println(U2U("\\u0041\\u0042\\u0043\\u000A\\u0031\\u0032\\u0033"));
}
}
