Arabic string in NSMutableArray or NSMutableDictionary - iphone

Question

I have a problem when I add an arabic string to NSMutableArray or NSMutableDictionary.
Example:
NSMutableDictionary *data = [[NSMutableDictionary alloc]init];
[data setObject:#"فرسان" forKey:#"name"];
NSLog(#"%#",data);
Output:
2012-01-18 21:55:05.646 aa[367:207] {
name = "\U0641\U0631\U0633\U0627\U0646";
}
my problem exactly i save this data to sqlite [data objectForKey:#"name"] its saved \U0641\U0631\U0633\U0627\U0646 and when fetch data to to put it in UILabel or anything like it the text be \U0641\U0631\U0633\U0627\U0646
Any Help? Thank you :)

When you log an object using %#, NSLog sends the description message to the object and prints the resulting string.
An NSDictionary responds to the description message by encoding its keys and values in a "safe" format, escaping non-ASCII characters using \U#### codes.
If you pass the Arabic string to NSLog directly, it will just print the string without the escape codes:
NSMutableDictionary *data = [[NSMutableDictionary alloc]init];
[data setObject:#"فرسان" forKey:#"name"];
NSLog(#"data = %#",data);
NSLog(#"string = %#", [data objectForKey:#"name"]);
Output:
2012-01-18 14:17:42.498 Animal[62723:f803] {
name = "\U0641\U0631\U0633\U0627\U0646";
}

If you don't like the way NSDictionary responds to description, you will have to write your own method to format a dictionary as a string and use it to log your dictionary.
Update
I have looked at the source code you posted that talks to sqlite. The problem is that you are turning the values array ([TableProperties allValues]) into a string using the %# format specifier. This sends the description method to the NSArray, which returns a string. Just like NSDictionary, NSArray formats the description string in a "safe" format, escaping non-ASCII characters using \U#### codes.
You need to write your own method that takes an array and turns it into a string and does not escape special characters. (It needs to escape quotes though.)
