我有这段代码，我想使用编码来阅读阿拉伯语和表情符号。

使用 JSON

在 .h 我使用两个数组

NSArray *news;

NSMutableData *data;

在.m

在 viewDidLoad

NSURL *url = [NSURL URLWithString:@"http://myServer.com/getmessages.php"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[[NSURLConnection alloc] initWithRequest:request delegate:self];

我已经使用了这些方法

-(void)connection: (NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{    
    data = [[NSMutableData alloc]init];    
}

-(void)connection: (NSURLConnection *)connection didReceiveData:(NSData *)theData
{   
    [data appendData:theData];  
}

-(void)connectionDidFinishLoading: (NSURLConnection *)connection
{

    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;


    news = [NSJSONSerialization JSONObjectWithData:data options:nil error:nil];

    if (news == nil || [news count] == 0) {

        UIAlertView *errorView = [[UIAlertView alloc]initWithTitle:@"Sorry!!" message:@" No News !!" delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles: nil];
        [errorView show];
    }

    [self.tableView reloadData];
}

-(void)connection: (NSURLConnection *)connection didFailWithError:(NSError *)error
{

    UIAlertView *errorView = [[UIAlertView alloc]initWithTitle:@"Error" message:@"The download could not complete - Plaese make sure                                            you're connected to either 3G or Wi-Fi" delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles: nil];
    [errorView show];

    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

}

我使用 UITableView

cell.newsLabel.text = [[news objectAtIndex:indexPath.row]objectForKey:@"Content"];

阿拉伯语和表情符号的编码是什么？以及如何在此代码中使用编码
