Java String Unicode Value

Question

How can I get the unicode value of a string in java?

For example if the string is \"Hi\" I need something like \\uXXXX\\uXXXX

Answer 1

This method converts an arbitrary String to an ASCII-safe representation to be used in Java source code (or properties files, for example):

public String escapeUnicode(String input) {
  StringBuilder b = new StringBuilder(input.length());
  Formatter f = new Formatter(b);
  for (char c : input.toCharArray()) {
    if (c < 128) {
      b.append(c);
    } else {
      f.format("\\u%04x", (int) c);
    }
  }
  return b.toString();
}
