JSON serialization double quote (") and single (') quote issue in iOS

Question

I'm facing JSON encoding issue.

I have submitted my data to server on below formate to save remarks.

{
Remarks = "test apple """ ";
}

Then while fetching the data from the server, I'm receiving different formate like output:

{
Remarks = "test apple \U00e2\U0080\U009c\U00e2\U0080\U009d\U00e2\U0080\U009d\U00e2\U0080\U009d\\n";
}

While submitting data I'm using JSON serialisation.

  NSData *jsonData
    = [NSJSONSerialization dataWithJSONObject: dict
                                      options: NSJSONWritingPrettyPrinted
                                        error: nil];

  if (jsonData)
  {
    NSString* jsonString
      = [[NSString alloc]
          initWithData: jsonData
              encoding: NSUTF8StringEncoding];
    NSLog(@"posting params: %@", jsonString);
  }

My question is why I'm not getting I have submitted. I'm facing only double quote (") and single (') symbols.

Any one have idea?

In your example there are only double quotes, correct? How do you send the data to the server. Is the example a part of your code? — Amin Negm-Awad, Mar 28 '18 at 08:30
To both questions? If it is an example from Objective-C code, there should be an error. — Amin Negm-Awad, Mar 28 '18 at 08:41
I found something.. iOS 11 default quotation mark changed to ‘ ’ and “ ” — Yalamandarao, Mar 28 '18 at 09:32
There is no default quotation mark in iOS. The default quotation marks in Objective-C are `@"` (opening) and `"` (closing). In Objective-C your code, if it is a string literal, makes no sense. Therefore please post the whole code. — Amin Negm-Awad, Mar 28 '18 at 10:25

You probably should escape your non-delimitating quotes : { Remarks = "test apple \"\"\" "; }

Likely, but as long as he is not quoting his whole code, it is guessing. – Amin Negm-Awad Mar 28 '18 at 10:26

iOS 11 has added "Smart Punctuation" to the keyboard settings.

This means when typing "Singapore" it will convert it to “Singapore”. The '"' are replaced by a '“' and '”' string. Those are different quotes.

So one option might be to also replace '“' and '”' by '\"'.

Smart Punctuation = No
