nextLine（）掃描儀的java不能正常工作（可能的，因爲統一的）

Question

我在這是應該在以下方式使用nextLine（）方法在掃描儀類中讀取文件的字符串：

some_string = "All the staff in the operating room has been specifically trained with a theoretical and practical 20-hour course.\xe2\x80\xa9Results: The overall average incidence of adverse events reported was determined by 4.8%, is consistent with the expectations of the study protocol, and is at a lower level than the average median rate of international studies (8.9%).\n" 

我以下列方式創建掃描對象：

Scanner br = new Scanner(new File("location of my file"), "UTF-8"); 

然後我做得到下一行：

while (br.hasNextLine()) { 
     System.out.println(br.nextLine()); 
} 

我得到：

>All the staff in the operating room has been specifically trained with a theoretical and practical 20-hour course. 
>Results: The overall average incidence of adverse events reported was determined by 4.8%, is consistent with the expectations of the study protocol, and is at a lower level than the average median rate of international studies (8.9%). 

看起來nextLine（）在有非ASCII字符時失敗。任何想法爲什麼發生這種情況

Answer 1

試試這個：

Scanner scanner = new Scanner(new File("the file"), "UTF-8").useDelimiter("\n"); 

    while (scanner.hasNext()) 
     System.out.println(scanner.next()); 

Answer 2

我打現在這個問題，遺憾的是掃描儀不使用非ASCII字符的工作，所以，當它到達它充當文件中的非ASCII字符結束。這就是爲什麼hasNext或hasNextLine返回false的原因！ 您可以更改方法並使用BufferedReader來讀取文件。

BufferedReader br = new BufferedReader(new FileReader(file)); 
String line; 
while ((line = br.readLine()) != null) { 
    System.out.println(line); 
}
