title: How to encode text with greek letters in a QR Code in android studio
body: <p>So i'm trying to make a QR code that when scanned it returns a text.
  Here's the code.</p>
  
  <pre><code>//GenerateCode is a button
  GenerateCode.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                  String name = PlayerAddEditText.getText().toString(); //PlayerAddEditText is an editText
                  try {
                      MultiFormatWriter multiFormatWriter = new MultiFormatWriter();
                      BitMatrix bitMatrix = multiFormatWriter.encode(name, BarcodeFormat.QR_CODE, 200, 200);
                      BarcodeEncoder barcodeEncoder = new BarcodeEncoder();
                      Bitmap bitmap = barcodeEncoder.createBitmap(bitMatrix);
                      QRCodeImageView.setImageBitmap(bitmap); //QRCodeImageView is an imageview
                  } catch (WriterException e) {
                      e.printStackTrace();
                  }
              }
          });
  </code></pre>
  
  <p>Everything works fine with english letters but when i enter greek letters in the editText and run the code the result string returns question marks.
  I try online QR generators to see if the problem is when i scan the QR code but it work fine with the online one's so i think the problem is my QR code generator code.But here's the code for getting the result(Scan QR Code).</p>
  
  <pre><code>//ScanCode is a button
  ScanCode.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View v) {
                  ScanCodeOnClick();
              }
          });
      }
      public void ScanCodeOnClick() {
          Dexter.withActivity(this)
                  .withPermission(Manifest.permission.CAMERA)
                  .withListener(new PermissionListener() {
                      @Override
                      public void onPermissionGranted(PermissionGrantedResponse response) {
                          ScanQRView.setResultHandler(AddPlayerActivity.this); // ScanQRView its a view that the camera is show(Instead of opening camera activity)
                          ScanQRView.startCamera();
                      }
  
                      @Override
                      public void onPermissionDenied(PermissionDeniedResponse response) {
                          toastMake("Πρέπει να πατήσεται αποδοχή"); //Translation:You have to accept the Permission
                      }
  
                      @Override
                      public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
  
                      }
                  })
                  .check();
      }
  
      @Override
      protected void onDestroy() {
          ScanQRView.stopCamera();
          super.onDestroy();
      }
  
      @Override
      public void handleResult(Result rawResult) {
          QRPlayerValues = rawResult.getText(); //QRPlayerValues is the result string;
          PlayerAddEditText.setText(QRPlayerValues);
          ScanQRView.startCamera(); 
      }
      public void toastMake(String message) {
          Toast.makeText(this, message, Toast.LENGTH_LONG).show();
      }

  <p>I'm using 2 phones to do that in the same application but i have a button to generate and a button to scan(Just for clarification).I need to be able to scan and get greek letters when the user input greek letters. </p>
