    <p>this is my working example Java code to encode QR code using ZXing with UTF-8 encoding, please note: you will need to change the path and utf8 data to your path and language characters </p> <pre><code>package com.mypackage.qr; import java.io.File; import java.io.IOException; import java.io.UnsupportedEncodingException; import java.nio.ByteBuffer; import java.nio.CharBuffer; import java.nio.charset.CharacterCodingException; import java.nio.charset.Charset; import java.nio.charset.CharsetEncoder; import java.util.Hashtable; import com.google.zxing.EncodeHintType; import com.google.zxing.MultiFormatWriter; import com.google.zxing.client.j2se.MatrixToImageWriter; import com.google.zxing.common.*; public class CreateQR { public static void main(String[] args) { Charset charset = Charset.forName("UTF-8"); CharsetEncoder encoder = charset.newEncoder(); byte[] b = null; try { // Convert a string to UTF-8 bytes in a ByteBuffer ByteBuffer bbuf = encoder.encode(CharBuffer.wrap("utf 8 characters - i used hebrew, but you should write some of your own language characters")); b = bbuf.array(); } catch (CharacterCodingException e) { System.out.println(e.getMessage()); } String data; try { data = new String(b, "UTF-8"); // get a byte matrix for the data BitMatrix matrix = null; int h = 100; int w = 100; com.google.zxing.Writer writer = new MultiFormatWriter(); try { Hashtable&lt;EncodeHintType, String&gt; hints = new Hashtable&lt;EncodeHintType, String&gt;(2); hints.put(EncodeHintType.CHARACTER_SET, "UTF-8"); matrix = writer.encode(data, com.google.zxing.BarcodeFormat.QR_CODE, w, h, hints); } catch (com.google.zxing.WriterException e) { System.out.println(e.getMessage()); } // change this path to match yours (this is my mac home folder, you can use: c:\\qr_png.png if you are on windows) String filePath = "/Users/shaybc/Desktop/OutlookQR/qr_png.png"; File file = new File(filePath); try { MatrixToImageWriter.writeToFile(matrix, "PNG", file); System.out.println("printing to " + file.getAbsolutePath()); } catch (IOException e) { System.out.println(e.getMessage()); } } catch (UnsupportedEncodingException e) { System.out.println(e.getMessage()); } } } </code></pre>

    1. COThis piece of code is working on my end also. Although, my code is not exactly the same. I am not saving the Image returned by the encode(). However, I am converting the BitMatrix to BitMap instance.

    2. COShaybc, your encoded QR Image might be scannable by some apps of android or Iphone but not all. You need to use "ISO-8859-1" instead of "UTF-8" for successful QR Image encoding. You can test your encoded Qr Image by using Red Laser App or QR Droid app from Google Play.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
