    <p>The <code>unichar</code> type is defined to be a 16-bit unicode value (eg, as indirectly documented in the <a href="https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html">description of the %C specifier</a>), and you can get a <code>unichar</code> from a given position in an <code>NSString</code> using <a href="https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/instm/NSString/characterAtIndex%3a"><code>characterAtIndex:</code></a>, or use <a href="https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/instm/NSString/getCharacters%3arange%3a"><code>getCharacters:range:</code></a> if you want to fill a C array of unichars from the <code>NSString</code> more quickly than by querying them one by one.</p> <p><code>NSUTF32StringEncoding</code> is also a valid string encoding, as are a couple of endian-specific variants, in case you want to be absolutely future proof. You'd get a C array of those using the much more longwinded <a href="https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/instm/NSString/getBytes%3amaxLength%3ausedLength%3aencoding%3aoptions%3arange%3aremainingRange%3a"><code>getBytes:maxLength:usedLength:encoding:options:range:remainingRange:</code></a>.</p> <p>EDIT: so, e.g.</p> <pre><code>NSString *str = @"A"; NSLog(@"16-bit unicode values are:"); for(int index = 0; index &lt; [str length]; index++) NSLog(@"%04x", [str characterAtIndex:index]); </code></pre>

    3. COThat's because `@"<"` is a string and hence an object, but `%C` expects a literal. You've sadly fallen into the fault line between the object-oriented world of Objective-C and the literal value old world of C. You'd use `%@` to specify an object, or `'<'` to place a character as a literal — though in both cases you'd need to be careful in general because unicode characters in source code don't necessarily survive compilation (despite `NSString` being fully unicode aware; it's a toolchain issue not a runtime issue).

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
