    <p>If you have <code>byte[]</code> or an <code>InputStream</code> (both binary data) you can get a <code>String</code> or a <code>Reader</code> (both text) with:</p> <pre><code>final String encoding = "UTF-8"; // "UTF16LE" or "UTF-16BE" byte[] b = ...; String s = new String(b, encoding); InputStream is = ...; BufferedReader reader = new BufferedReader(new InputStreamReader(is, encoding)); for (;;) { String line = reader.readLine(); } </code></pre> <p>The reverse process uses:</p> <pre><code>byte[] b = s.geBytes(encoding); OutputStream os = ...; BufferedWriter writer = new BufferedWriter(new OuputStreamWriter(os, encoding)); writer.println(s); </code></pre> <p>Unicode is a numbering system for all characters. The UTF variants implement Unicode as bytes.</p> <hr> <p><em><strong>Your problem:</em></strong></p> <p>In normal ways (web service), you would already have received a <code>String</code>. You could write that string to a file using the Writer above for instance. Either to check it yourself with a <strong>full Unicode font</strong>, or to pass the file on for a check.</p> <p>You need (?) to check, which UTF variant the text is in. For Asiatic scripts UTF-16 (little endian or big endian) are optimal. In XML it would be defined already.</p> <hr> <p><em><strong>Addition:</em></strong></p> <p><a href="http://docs.oracle.com/javase/7/docs/api/java/io/FileWriter.html" rel="nofollow">FileWriter</a> writes to a file using the default encoding (from operating system on your machine). Instead use:</p> <pre><code>new OutputStreamWriter(new FileOutputStream(new File("...")), "UTF-8") </code></pre> <p>If it is a binary PDF, as @bobince said, use just a FileOutputStream on byte[] or InputStream.</p>

    2. CONo problem, see Addition in my answer. I seldom use FileWriter myself, as the app then may use a different encoding on a different computer.

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.
