Excel 电子表格中的字符编码（以及使用什么 Java 字符集对其进行解码）

Java
import Java.io.FileInputStream;
import Java.io.IOException;
import Java.io.InputStream;
import Java.nio.charset.StandardCharsets;
public class excelCharacterEncoding {
    public static void mAIn(String[] args) {
        try {
            String filePath = "path/to/excel.xlsx";
            InputStream inputStream = new FileInputStream(filePath);
            
            byte[] bytes = new byte[inputStream.avAIlable()];
            inputStream.read(bytes);
            
            String utf8String = new String(bytes, StandardCharsets.UTF_8);
            String gbkString = new String(bytes, "GBK");
            String isoString = new String(bytes, "ISO-8859-1");
            
            System.out.println("UTF-8解码结果：" + utf8String);
            System.out.println("GBK解码结果：" + gbkString);
            System.out.println("ISO-8859-1解码结果：" + isoString);
            
            inputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
