我为什么要来？当我尝试从java中的文本文件中读取ä字符时？ [英] Why am i getting ?? when i try to read ä character from a text file in java?

问题描述

我正在尝试从文本文件中读取文本。有一些特殊字符，如å，ä和ö。当我创建一个字符串并打印出该字符串然后我得到??从这些特殊人物。我使用以下代码：

I am trying to read text from a text file. There are some special characters like å,ä and ö. When i make a string and print out that string then i get ?? from these special characters. I am using the following code:

File fileDir = new File("files/myfile.txt");

BufferedReader br = new BufferedReader(new InputStreamReader(
                      new FileInputStream(fileDir), "UTF8"));

String strLine;
while ((strLine = br.readLine()) != null)   {
    System.out.println("strLine: "+strLine);
}

任何人都可以告诉我这是什么问题。我希望strLine显示并保存å，ä和ö，因为它们在文本文件中。在此先感谢。

Can anybody tell me whats the problem. I want strLine to show and save å, ä and ö as they are in text file. Thanks in advance.

推荐答案

问题可能不在于文件，而在于您尝试打​​印的控制台。我建议您按照以下步骤操作

The problem might not be with the file but with the console where you are trying to print. I suggest you follow the following steps

1. 确保您正在阅读的文件采用UTF-8编码。


2. 确保要打印的控制台具有正确的编码/字符集以显示这些字符
