XML下載NSUTF8String編碼問題

我已經使這種方法從URL下載XML。問題是編碼字符。XML下載NSUTF8String編碼問題

-(void) scaricamentoXML{ 
    /*Save XML IN LOCALE*/ 
    NSString* docsDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]; 
    NSLog(@"Doc dir: %@:",docsDir); 
    //dichiaro il file locale in cui salvare i dati XML 
    NSString* fileToDownload = @"provaXML.xml"; 

    NSString *hostURLString = @"http://demo.gigamips.com/rss.php?authkey=12345"; 
    NSURL *xmlURL = [NSURL URLWithString:hostURLString]; 
    NSLog(@"xmlURL = %@", xmlURL); 
    //gestione codifica UTF-8 
    NSError *error; 
    NSString *dataString = [[NSString alloc] initWithContentsOfURL:xmlURL encoding:NSASCIIStringEncoding error:&error]; 
    NSLog(@"DataString = %@", dataString); 
    //NSData *xml = [[NSData alloc]initWithContentsOfURL:xmlURL]; 
    NSData *xml = [dataString dataUsingEncoding:NSUTF8StringEncoding]; 
    //creo una stringa di appoggio in encoding UTF8 - verificare se funziona 
    NSString *str = [[NSString alloc] initWithData:xml encoding:NSUTF8StringEncoding]; 
    NSLog(@"NSData xml = %@", xml); 
    //NSString *newStr = [[NSString alloc] initWithData:xml encoding:NSUTF8StringEncoding]; 
    //NSLog(@"newStr = %@", newStr); 
    NSString *filePath = [docsDir stringByAppendingPathComponent: fileToDownload]; 

    //[xml writeToFile: filePath atomically: NO]; 
    [str writeToFile: filePath atomically: NO]; 
    /*Save XML IN LOCALE*/ 


    /*SALVO LE IMMAGINI MINI IN LOCALE*/ 
    AuthParserImages *parser=[[AuthParserImages alloc]init]; 
    entryArray=[parser startParserLocale:@"provaXML"]; 
    GestioneImages *gi = [[GestioneImages alloc]init]; 
    for(int i =0; i< [entryArray count];i++){ 
     item=[entryArray objectAtIndex:i]; 
     [gi saveImageLocal:item.urlImageLow :item.id]; 
    } 
    /*SALVO LE IMMAGINI MINI IN LOCALE*/ 


    /*CREA IL FILE GESTIONE NEW*/ 
    gp = [[GestionePlist alloc]init]; 
    [gp savePlist:@"begin"]; 
    /*CREA IL FILE GESTIONE NEW*/ 

    [self controlloXML]; 
    [activityIndicator stopAnimating]; 

}

我看不到的特殊卡拉科特像'或重點ù - A - ò等....
