Try either

NSString *result =[sourceString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

or

NSString *result =(NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
                                                               (CFStringRef)sourceString,
                                                               NULL,
                                                               (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",
                                                               CFStringConvertNSStringEncodingToEncoding(encoding));
