Nilai parameter yang diharapkan, didapat "è saat mengirim email menggunakan Amazon SES di C#

Saya telah menggunakan Amazon SES untuk mengirim email dengan lampiran. Jika saya melampirkan lampiran dengan nama bahasa Inggris, itu berfungsi dengan benar tetapi jika saya melampirkan resume Cina, itu menimbulkan kesalahan Nilai parameter yang diharapkan, dapatkan "è. Deskripsi kesalahan tidak jelas dan saya mencoba menyandikan dengan format berbeda tetapi mendapatkan kesalahan yang sama.

Di bawah ini adalah kode yang saya gunakan untuk membuat pesan email dan mengirimnya

public static MailResponse SendRawEmail(String from, List<string> to,List<string> ccAddresses,List<string> bccAddresses, String Subject, string body=null,List<string> attachments=null, String html = null,Salesforce.Contact[] contacts=null, String replyTo = null, String returnPath = null)
{
    MailResponse mresponse = new MailResponse();
    try
    {
        MailMessage mailMessage = new MailMessage();
        mailMessage.From = new MailAddress(from);


       mailMessage.Body = body;

        mailMessage.Subject = Subject;
        mailMessage.SubjectEncoding = Encoding.UTF8;
        foreach (string attachment in attachments)
            mailMessage.Attachments.Add(new System.Net.Mail.Attachment(attachment));

        if (body != null)
        {
            AlternateView plainView = AlternateView.CreateAlternateViewFromString(body, Encoding.UTF8, "text/plain");
            mailMessage.AlternateViews.Add(plainView);
        }

        if (html != null)
        {
            AlternateView htmlView = AlternateView.CreateAlternateViewFromString(html, Encoding.UTF8, "text/html");
            mailMessage.AlternateViews.Add(htmlView);
        }

        RawMessage rawMessage = new RawMessage();

        foreach (String toAddress in to)
        {
            mailMessage.To.Add(new MailAddress(toAddress));

            using (MemoryStream memoryStream = ConvertMailMessageToMemoryStream(mailMessage))
            {
