Chinese characters to Unicode Escape

Question

I'd like to implement a function that convert Chinese string into Unicode escape codes. Just like what the native2ascii doing.
I can convert single bytes with charToHex but have no clue on dealing double byte character. Any hints?

Answer 1

I think unicode escapes can be obtained through the tool Native2Ascii from a file. However, if you would a code, the following might be an example.
public class UnicodeTool{
static String byteToHex(byte b) {
      // Returns hex String representation of byte b
      char hexDigit[] = {'0', '1', '2', '3', '4', '5', '6', '7','8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
      char[] array = { hexDigit[(b >> 4) & 0x0f], hexDigit[b & 0x0f] };
      return new String(array);
   }   // end of method byteToHex
    static String charToHex(char c) {
      // Returns hex String representation of char c
      byte hi = (byte) (c >>> 8);
      byte lo = (byte) (c & 0xff);
      return byteToHex(hi) + byteToHex(lo);
   }   // end of method charToHex
static String toUnicodeFormat(char c){
           // int n = (int)c;
           //String body = Integer.toHexString(n);
           String body=charToHex(c); 
            String zeros = "000";
             return ("\\u" + zeros.substring(0, 4-body.length()) + body);
    } //end of method toJavaUnicodeFormat
/*   public static void main(String[] args){
    String str = "09Az";//example of a string
    char[] chs = str.toCharArray();
    for(int j=0;j<chs.length;j++)
     System.out.println(toUnicodeFormat(chs[j]));
}
