Char encoding issue on url, non-english chars -iOS

Question

I am trying to do search on youtube. This code works fine with english chars. But when I try to type non-english letters like ö, ü, ş returns null.

NSString *kStrJsonURL = [NSString stringWithFormat:@"http://suggestqueries.google.com/complete/search?hl=en&ds=yt&client=youtube&hjson=t&cp=1&q=%@&key=API_KEY&format=5&alt=jsonc&callback=?", self.searchField.text];
    NSURL *url = [NSURL URLWithString:kStrJsonURL];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id getJSON) {
        _JSON = getJSON;
        NSLog(@"%@", _JSON);

    } failure:nil];
    [operation start];

I've tried to encode url like this but doesn't work..

[self.searchField.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]

Your code should like this:

//Added this line
[self.searchField.text stringByReplacingOccurrencesOfString:@" " withString:@"+"];
//
    NSString *kStrJsonURL = [NSString stringWithFormat:@"http://suggestqueries.google.com/complete/search?hl=en&ds=yt&client=youtube&hjson=t&cp=1&q=%@&key=API_KEY&format=5&alt=jsonc&callback=?", self.searchField.text];
        NSURL *url = [NSURL URLWithString:[kStrJsonURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
        NSURLRequest *request = [NSURLRequest requestWithURL:url];
        AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id getJSON) {
            _JSON = getJSON;
            NSLog(@"%@", _JSON);

    } failure:nil];
    [operation start];

I just tried this and checked the failure and I am getting this error: NSDebugDescription = "Unable to convert data to string around character 1."; — onivi, Oct 29 '13 at 16:06
