NSString convert string to NSData using encoding

Question

I have got small issue in my app.

I make NSMutableURLRequest and send body to my webserice.

jsonRequest = @"{\"s\":\"deón\"}";

NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];

I need change "ó" symbol to \u00F3.

Any idea?

I would suggest you another way around if you want to deploy on target >=iOS5. It involves more steps, but you can be sure about the correct result, it's less error prone.

NSDictionary * jsonDict = @{ @"s" : @"deón" };    
NSData * requestData = [NSJSONSerialization dataWithJSONObject:jsonDict options:0 error:nil];
