    <p>I'm trying to convert an application from Java + Swing to C++ + Qt. At one point I had to deal with some Unicode intermediates. In Java, this was fairly easy:</p> <pre><code>private static String[] hiraganaTable = { "\u3042", "\u3044", "\u3046", "\u3048", "\u304a", "\u304b", "\u304d", "\u304f", "\u3051", "\u3053", ... } </code></pre> <p>...whereas in C++ I'm having problems:</p> <pre><code>QString hiraganaTable[] = { "\x30\x42", "\x30\x44", "\x30\x46", "\x30\x48", "\x30\x4a", "\x30\x4b", "\x30\x4d", "\x30\x4f", "\x30\x51", "\x30\x53", ... }; </code></pre> <p>I couldn't use \u in VS2008 because I got a heap of warnings of the form:</p> <blockquote> <p>character represented by universal-character-name '\u3042' cannot be represented in the current code page (1250)</p> </blockquote> <p>And don't call me stupid, I tried to use File->Advanced Save Options to no avail, the codepage didn't seem to change at all. Seems like this is a known problem: <a href="https://stackoverflow.com/questions/688760/how-to-create-a-utf-8-string-literal-in-visual-c-2008">How to create a UTF-8 string literal in Visual C++ 2008</a></p> <p>The table I'm using is fairly short, so with the help of Vim and some introductory-level regexp-magic, I was able to convert it to <strong>\x30\x42</strong> notation. Unfortunately, the QStrings would not initialize properly from such an input. I tried everything. fromAscii(), fromUtf8(), fromLocal8Bit(), QString(QByteArray), the works. Then, trying to write U+3042 without BOM to a file and then viewing it in hex mode, I found out it actually turns out to be <strong>"E3 81 82"</strong>. Suddenly, an entry like this seemed to work with <strong>QString::fromAscii()</strong>. Now I'm left wondering how much does exactly the "U+" stand for in "U+3042" (since 0xE38182 - 0x3042 = E35140, maybe I'd better add this Magic Constant to all my would-be Unicode chars?). How should I proceed from here to get an array of proper UTF-8 strings?</p>

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.
