Question

In this function, I get the selected emoticon from NSTableView from the NSArrayController connected to an IBOutlet called emotes. The string in the selected NSArray contains UTF8 characters that is sent to the clipboard.

// Get Selected Emoticon
NSArray * selectedemote = [emotes selectedObjects];
NSLog(@"%@",[selectedemote valueForKey:@"emote"]);
// Send to Clipboard
[self copyToClipboard:[NSString stringWithFormat:@"%@",[selectedemote valueForKey:@"emote"]]];

The problem is with the NSArray itself. It seems to output the UTF8 string as a hexadecimal. Here is what the string looks like from the NSLog function:

2010-08-23 11:23:56.411 Emoticon[7919:a0f] (
    "\\(\U2579\U30ee\U2579 )/"
)

Is there a possible way of converting the UTF-8 hex to a UTF-8 characters? Thanks.

I solved the issue. The solution is to use the NSEntityDescription and init it with the objectAtIndex:0 in the NSArray with the selected cell. Using the NSEntityDescription, I got the value for Emote.

-(IBAction)sendtoclipboard:(id)sender
{
    // Get Selected Emoticon
    NSArray * selectedemote = [emotes selectedObjects];
    NSEntityDescription *entity = [selectedemote objectAtIndex:0];
    NSString * tmpemote = [NSString stringWithFormat:@"%@",[entity valueForKey:@"emote"]];
    NSLog(@"%@", [entity valueForKey:@"emote"]);
    //Send to Clipboard
    [self copyToClipboard:tmpemote];
}

The result:

2010-09-07 20:03:26.488 Emoticon[45764:a0f] \(╹ヮ╹ )/
