ASIFormDataRequest encoding unicode characters

Question

I am creating the API data via PHP and it creates unicode characters not correctly.

For example ü returned as \u00fc

On ASIFormDataRequest I have tried to parsed it correctly but I couldnt manage to do it. What I ve tried so far are:

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setResponseEncoding:NSUTF8StringEncoding];    
[request addRequestHeader:@"content-type" value:@"text/json; charset=utf-8"];

I am wondering how can I parse the unicode characters correctly?

Be aware that `ASIHttpRequest` is deprecated and should not longer be used. — rckoenes, Apr 13 '15 at 14:56
ü "LATIN SMALL LETTER U WITH DIAERESIS" is \u00fc in UTF-16. In UTF-8 it is 0xc3 0xbc. There is a mis-match between the character encoding and specifying "charset=utf-8". — zaph, Apr 13 '15 at 15:19

Solution 1: set defaultResponseEncoding when creating ASIFormDataRequest.

request.defaultResponseEncoding = NSUTF8StringEncoding;

Solution 2: set responseEncoding before calling responseString.

- (void)requestFinished:(ASIHTTPRequest *)request {
    request.responseEncoding = NSUTF8StringEncoding;
    NSLog(@"%@", request.responseString);
}
