Arabic text to display

Question

I have text file with arabic words. I need to read file (this part is done) and to display some words from file. But it does not shows arabic symbols. How can I make it?

Answer 1

I found solution:
private final String readUnicodeFileUTF8(String filename) {
       StringBuffer sb = new StringBuffer(256);
       try {
           int[] surrogatePair = new int[2];
           InputStream is = this.getClass().getResourceAsStream(filename);
           int val = 0;
           int unicharCount = 0;
           while ((val = readNextCharFromStreamUTF8(is))!=-1) {
               unicharCount++;
               if (val <= 0xFFFF) {
                   // if first value is the Byte Order Mark (BOM), do not add
                   if (! (unicharCount == 1 && val == 0xFEFF)) {
                       sb.append((char)val);
               } else {
                   supplementCodePointToSurrogatePair(val, surrogatePair);
                   sb.append((char)surrogatePair[0]);
                   sb.append((char)surrogatePair[1]);
           is.close();
       } catch (Exception e) {};
       return new String(sb);
   private final static int readNextCharFromStreamUTF8(InputStream is) {
       int c = -1;
       if (is==null) return c;
       boolean complete = false;
       try {
           int byteVal;
           int expecting=0;
           int composedVal=0;
           while (!complete && (byteVal = is.read()) != -1) {
               if (expecting > 0 && (byteVal & 0xC0) == 0x80) {  /* 10xxxxxx */
                   expecting--;
                   composedVal = composedVal | ((byteVal & 0x3F) << (expecting*6));
                   if (expecting == 0) {
                       c = composedVal;
                       complete = true;
                       //System.out.println("appending: U+" + Integer.toHexString(composedVal) );
               } else {
                   composedVal = 0;
                   expecting = 0;
                   if ((byteVal & 0x80) == 0) {    /* 0xxxxxxx */
                       // one byte character, no extending byte expected
                       c = byteVal;
                       complete = true;
                       //System.out.println("appending: U+" + Integer.toHexString(byteVal) );
                   } else if ((byteVal & 0xE0) == 0xC0) {   /* 110xxxxx */
                       expecting = 1;  // expecting 1 extending byte
                       composedVal = ((byteVal & 0x1F) << 6);
                   } else if ((byteVal & 0xF0) == 0xE0) {   /* 1110xxxx */
                       expecting = 2;  // expecting 2 extending bytes
                       composedVal = ((byteVal & 0x0F) << 12);
                   } else if ((byteVal & 0xF8) == 0xF0) {   /* 11110xxx */
                       expecting = 3;  // expecting 3 extending bytes
                       composedVal = ((byteVal & 0x07) << 18);
                   } else {
                       // non conformant utf-8, ignore or catch error
       } catch (Exception e) {
           System.out.println(e.toString());
       return c;
   private final static void supplementCodePointToSurrogatePair(int codePoint, int[] surrogatePair) {
       int high4 = ((codePoint >> 16) & 0x1F) - 1;
       int mid6 = ((codePoint >> 10) & 0x3F);
       int low10 = codePoint & 0x3FF;
       surrogatePair[0] = (0xD800 | (high4 << 6) | (mid6));
       surrogatePair[1] = (0xDC00 | (low10));
