如果使用挪威语字母,则附件的名称会被错误解码

Question

我有这段代码创建附件并发送电子邮件.如果文件名包含æ,ø或æ,则名称将被完全销毁.

如果我删除挪威字母,一切都很好

        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);

如何正常工作？

尝试更改attachment.NameEncoding = Encoding.UTF8;为attachment.NameEncoding = Encoding.Unicode;.
