如何解决 LogOutputStream 中文乱码问题？

不管是 org.apache.commons.exec 工具包，还是 org.zeroturnaround.exec 工具包，都会出现中文乱码问题，请问有办法解决吗？ 例子： org.apache.commons.exec 工具包的 demo：

package utils.exec;

import cn.hutool.core.io.LineHandler;
import lombok.NonNull;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.exec.*;

import java.util.concurrent.TimeUnit;

@Slf4j
public class LocalCommandUtils {
    private static final long TIMEOUT = 1;
    private static final TimeUnit TIME_UNIT = TimeUnit.DAYS;

    public static String execCmd(String cmd) {
        return execCmd(cmd, line -> {});
    }

    public static String execCmd(String cmd, LineHandler lineHandler) {
        return execCmd(cmd, lineHandler, TIMEOUT, TIME_UNIT);
    }

    public static String execCmd(String cmd, LineHandler lineHandler, @NonNull long timeout, @NonNull TimeUnit unit) {
        DefaultExecutor executor = new DefaultExecutor();
        ExecuteWatchdog watchdog = new ExecuteWatchdog(unit.toMillis(timeout));
        StringBuilder output = new StringBuilder();
        try {
            CommandLine cmdLine = CommandLine.parse(cmd);
            executor.setWatchdog(watchdog);
            executor.setStreamHandler(new PumpStreamHandler(new LogOutputStream() {
                @Override
                protected void processLine(String line, int logLevel) {
                    lineHandler.handle(line);
                    output.append(output.length() > 0 ? "\n" : "").append(line);
                }
            }));
            executor.execute(cmdLine);
            log.info("exec command:[{}] output:[\n{}\n]", cmd, output);
        } catch (Exception e) {
            log.error("exec command:[{}] failed, output:[\n{}\n]", cmd, output, e);
        }
        return output.toString();
    }

    public static void main(String[] args) {
        execCmd("ping 127.0.0.1", log::info);
    }
}

org.zeroturnaround.exec 工具包的 demo：

package utils.ztexec;

import cn.hutool.core.io.LineHandler;
import lombok.NonNull;
import lombok.extern.slf4j.Slf4j;
import org.zeroturnaround.exec.ProcessExecutor;
import org.zeroturnaround.exec.stream.LogOutputStream;

import java.util.concurrent.TimeUnit;

@Slf4j
public class LocalCommandUtils {
    private static final long TIMEOUT = 1;
    private static final TimeUnit TIME_UNIT = TimeUnit.DAYS;

    public static String execCmd(String cmd) {
        return execCmd(cmd, line -> {});
    }

    public static String execCmd(String cmd, LineHandler lineHandler) {
        return execCmd(cmd, lineHandler, TIMEOUT, TIME_UNIT);
    }

    public static String execCmd(String cmd, LineHandler lineHandler, @NonNull long timeout, @NonNull TimeUnit unit) {
        StringBuilder output = new StringBuilder();
        try {
            new ProcessExecutor()
                    .commandSplit(cmd)
                    .timeout(timeout, unit)
                    .redirectOutput(new LogOutputStream() {
                        @Override
                        protected void processLine(String line) {
                            lineHandler.handle(line);
                            output.append(output.length() > 0 ? "\n" : "").append(line);
                        }
                    })
                    .execute();
            log.info("exec command:[{}] output:[\n{}\n]", cmd, output);
        } catch (Exception e) {
            log.error("exec command:[{}] failed, output:[\n{}\n]", cmd, output, e);
        }

        return output.toString();
    }

    public static void main(String[] args) {
        execCmd("ping 127.0.0.1", log::info);
    }
}
