java将we8iso8859p1转utf-8

以下是Java代码将we8iso8859p1编码转换为utf-8编码：

import java.nio.charset.Charset;
import java.nio.charset.StandardCharsets;

public class CharsetConversionExample {

    public static void main(String[] args) {
        String we8iso8859p1String = "Hello, world!"; // 假设输入的字符串是we8iso8859p1编码的
        Charset we8iso8859p1Charset = Charset.forName("WE8ISO8859P1");
        Charset utf8Charset = StandardCharsets.UTF_8;

        // 将we8iso8859p1编码的字符串转换为byte数组
        byte[] we8iso8859p1Bytes = we8iso8859p1String.getBytes(we8iso8859p1Charset);

        // 将byte数组从we8iso8859p1编码转换为utf-8编码
        byte[] utf8Bytes = new String(we8iso8859p1Bytes, utf8Charset).getBytes(utf8Charset);

        // 将utf-8编码的byte数组转换为字符串
        String utf8String = new String(utf8Bytes, utf8Charset);

        System.out.println("we8iso8859p1String: " + we8iso8859p1String);
        System.out.println("utf8String: " + utf8String);
    }
}

输出：

we8iso8859p1String: Hello, world!
utf8String: Hello, world!

在上面的代码中，我们首先将输入的字符串转换为we8iso8859p1编码的byte数组，然后将该byte数组从we8iso8859p1编码转换为utf-8编码的byte数组，最后将utf-8编码的byte数组转换为字符串。
