are you picky with using Unicode because with java its more simple if you write your program to use  dec  value or  HTML-Code  then you can simply cast data types between char and int  char a   98  char b    b   char c    char   b 0002    System out println a   System out println  int b   System out println  int c   System out println c     Gives this output  b 98 100 d

First  I get the high side of the char  After  get the low side  Convert all of things in HexString and put the prefix   int hs    int  c   gt  gt  8  int ls   hs  amp  0x000F   String highSide   Integer toHexString hs   String lowSide   Integer toHexString ls   lowSide   Integer toHexString hs  amp  0x00F0   String hexa   Integer toHexString   int  c     System out println c          u  highSide lowSide hexa

You can do it for any Java char using the one liner here   System out println     u    Integer toHexString        0x10000  substring 1       But it s only going to work for the Unicode characters up to Unicode 3 0  which is why I precised you could do it for any Java char   Because Java was designed way before Unicode 3 1 came and hence Java s char primitive is inadequate to represent Unicode 3 1 and up  there s not a  one Unicode character to one Java char  mapping anymore  instead a monstrous hack is used    So you really have to check your requirements here  do you need to support Java char or any possible Unicode character

If you have Java 5  use char c        String s   String format     u 04x    int c    If your source isn t a Unicode character  char  but a String  you must use charAt index  to get the Unicode character at position index   Don t use codePointAt index  because that will return 24bit values  full Unicode  which can t be represented with just 4 hex digits  it needs 6   See the docs for an explanation    EDIT  To make it clear  This answer doesn t use Unicode but the method which Java uses to represent Unicode characters  i e  surrogate pairs  since char is 16bit and Unicode is 24bit  The question should be   How can I convert char to a 4-digit hex number   since it s not  really  about Unicode

I found this nice code on web   import java io BufferedReader  import java io IOException  import java io InputStreamReader   public class Unicode    public static void main String   args    System out println  Use CTRL C to quite to program         Create the reader for reading in the text typed in the console   InputStreamReader inputStreamReader   new InputStreamReader System in   BufferedReader bufferedReader   new BufferedReader inputStreamReader    try     String line   null    while   line   bufferedReader readLine    length    gt  0        for  int index   0  index  lt  line length    index                Convert the integer to a hexadecimal code        String hexCode   Integer toHexString line codePointAt index   toUpperCase               but the it must be a four number value        String hexCodeWithAllLeadingZeros    0000    hexCode        String hexCodeWithLeadingZeros   hexCodeWithAllLeadingZeros substring hexCodeWithAllLeadingZeros length  -4          System out println    u    hexCodeWithLeadingZeros                catch  IOException ioException           ioException printStackTrace               Original Article
