Question

I’m working with a web service and using sbjson to parse received data like this:

NSDictionary *response = [[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding]JSONValue];

It works well but failed with a json including binary data (application/pdf)
and I got this in the console:

-JSONValue failed. Error trace is: (
    "Error Domain=org.brautaset.JSON.ErrorDomain Code=6 \"Invalid high character in surrogate pair\" UserInfo=0x1e0e1700 {NSLocalizedDescription=Invalid high character in surrogate pair}",
    "Error Domain=org.brautaset.JSON.ErrorDomain Code=6 \"Broken unicode character\" UserInfo=0x1e0e1740 {NSUnderlyingError=0x1e0e1720 \"Invalid high character in surrogate pair\", NSLocalizedDescription=Broken unicode character}",

)

(lldb) 

Now I wonder how to solve it without move to another json library.
Are there other people else who have ever coped with json including binary?
Thanks!

From: json.org “JSON is a text format”. Base64 encode the binary data.

See SO question “Binary Data in JSON String”
