这个是jchardet的地址

也有人写了用getEncoding
import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStreamReader;

public class FileCharset {
public static void main(String[] args) throws FileNotFoundException {
InputStreamReader isr = new InputStreamReader(new FileInputStream(
"Service02.asp"));
System.err.println(isr.getEncoding());
BufferedReader br = new BufferedReader(isr);
}
}

但是不起作用
getEncoding gives you the encoding the reader is using, not what the file is
using. The problem is that there isn't anything in the file that says what
encoding it is using. You can look at some byte patterns to try to
determine whether it's UTF-8, UTF-16BE, or whatever but there's no perfect
rule for it.
