In my application I'm uploading a file which has Swedish characters in file name. It works fine. But when I try to download it, I get an error: "An invalid character was found in the mail header" ..Could you help regarding this Please see my code

public ActionResult Download(Guid id)
{
   var attachment = AttachmentService.GetAttachmentById(id);
   var cd = new ContentDisposition
                {
                  FileName = Utility.GetCleanedFileName(((FileAttachment)attachment).FileName),
                  Inline = false,
                };

   var file = File("\\App_Data" +((FileAttachment)attachment).FilePath, "Application");

   Response.ClearHeaders();
   Response.Clear();
   Response.ContentType = file.ContentType;
   Response.AppendHeader("Content-Disposition", cd.ToString());

Please try to encode the filename using HttpUtility.UrlPathEncode.
