c# - 如果使用挪威字母，附件名称解码错误

Question

我有这段代码可以创建附件并发送电子邮件。如果文件名中包含 æ、ø 或 æ，则该文件名将被完全销毁。

如果我删除挪威字母，一切正常

        var stream = new MemoryStream();
        doc.Save(stream, SaveFormat.Docx);

        mail.From = new MailAddress("no-replay@email.no");
        mail.To.Add("my@email.no");
        mail.IsBodyHtml = true;
        mail.Subject = "Attachments test";
        mail.Body = "Hei,<br /><br />";
        stream.Seek(0, SeekOrigin.Begin);

        var attachment = new Attachment(stream, "Name Å Æ Ø.docx", "application/vnd.openxmlformats-officedocument.wordprocessingml.document");
        attachment.NameEncoding = Encoding.UTF8;
        mail.Attachments.Add(attachment);
        var smtp = new SmtpClient("smtp.server.com") {Port = 25};
        smtp.Send(mail);

如何使这项工作正常进行？
