When UnZip a zip,Inside File's FileName is Garbled code (ZipEntry.Name) ?

[SummerCSharp]

The source filename is "测试.pdf"，It contains Chinese characters,but entryName is Garbled code.
I need some setting?

`public static void Main()
{
string zipFilePath = "";
string extractPath = "";
string password = ""; // 输入密码
try
{
using (FileStream fileStream = File.OpenRead(zipFilePath))
{
using (ZipInputStream zipStream = new ZipInputStream(fileStream))
{
if (!string.IsNullOrEmpty(password))
{
zipStream.Password = password; // 设置密码
}

                ZipEntry entry;
                while ((entry = zipStream.GetNextEntry()) != null)
                {
                    if (!entry.IsFile)
                    {
                        continue;
                    }

                    string entryName = entry.Name;
                    string fullPath = Path.Combine(extractPath, entryName);

                    string directory = Path.GetDirectoryName(fullPath);
                    if (!Directory.Exists(directory))
                    {
                        Directory.CreateDirectory(directory);
                    }

                    using (FileStream outputFile = File.Create(fullPath))
                    {
                        byte[] buffer = new byte[4096];
                        int bytesRead;
                        while ((bytesRead = zipStream.Read(buffer, 0, buffer.Length)) > 0)
                        {
                            outputFile.Write(buffer, 0, bytesRead);
                        }
                    }
                }
            }

        }

        Console.WriteLine("解压缩完成！");
    }
    catch (Exception ex)
    {
        Console.WriteLine("解压缩出错：" + ex.Message);
    }
}`
