Ошибка синтаксического анализа цели кодирования XML c

Я пытаюсь разобрать XML с помощью AFXMLRequestOperation, но синтаксический анализ останавливается, когда найдена строка «ç», я точно не знаю, как разобрать этот кусок строки, вот код:

AFXMLRequestOperation * op = [AFXMLRequestOperation XMLParserRequestOperationWithRequest:req success:^(NSURLRequest *request, NSHTTPURLResponse *response, NSXMLParser *XMLParser)
{
    NSLog(@"XML document %@", XMLParser);
    NSLog(@"response %@",response);

    XMLParser.delegate = self;
    [XMLParser parse];

}failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSXMLParser *XMLParser) {
    NSLog(@"response %@",response);
    NSLog(@"Error %@", error);
}];


- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{    
    NSString *correctString = [NSString stringWithCString:[string cStringUsingEncoding:NSISOLatin1StringEncoding] encoding:NSUTF8StringEncoding];
    NSLog(@"string %@",correctString);
}

и вот XML:
