推荐答案

文件使用特定的字符集编写.

而且"unicode"还不足以识别正在使用哪个字符集.常见的(但不是唯一的可能性)包括8位和16位变体，其中16位变体包括字节顺序.

确定字符集后，然后使用适当的编码打开文件.

打开具有特定编码的文件的一个示例如下

InputStreamReader(stream，"UTF-8")


还要记住，仅仅因为您正确阅读了它并不意味着您可以正确显示它.这是两个不同的部分.

Files are written with a specific character set.

And "unicode" is not enough to identify which character set is is use. Common (but not the only possibility) include 8 bit and 16 bit variations, where the 16 bit variation includes byte order.

AFTER you determine the character set then you open the file using the appropriate encoding.

ONE example of opening a file like that with a specific encoding is as follows

InputStreamReader(stream, "UTF-8")


Further keep in mind that just because you read it correctly it does not mean that you can display it correctly. Those are two distinct parts.

快速而简单:

quick and simple:

Reader oReader = new InputStreamReader(new FileInputStream("file"), "UTF-8"));
String strUTF8Text = null;

while(true){ // infinit loop
  String strLine = oReader.readLine();
  if(null== strLine) break; // exit point
  strUTF8Text += strLine;
}
