I'm using SendGridPlus API for sending e-mails with SendGrid. Everything works fine. But I have a problem with spanish characters like á or é when I include them in substitution values in the header.
For instance if I include Que día más bueno hace I receive Que d?a m?s bueno hace.
Here is the code:
[Test]
public void TestSendGrid()
{
//create a new message object
var message = Mail.GetInstance();
var recipients = new List<string>();
//You could loop through your dataset here and add each recipient, up to 1000 recipients per message
recipients.Add("[email protected]");
recipients.Add("[email protected]");
//We want to add the recipients to the X-SMTPAPI header
message.Header.AddTo(recipients);
//Even though we added recipients to the Header, the envelope must also have a valid recipient
message.AddTo("[email protected]");
//set the sender
message.From = new MailAddress(From);
//set the message body
message.Html = "<html><p>Hello *|USERNAME|*</p><p>World *|MESSAGE|* </p></html>";
//This replacement key must exist in the message body
var replacementKey = "*|USERNAME|*";
//There should be one value for each recipient in the To list
var substitutionValues = new List<string> { "Mr Foo", "Mrs Raz" };
message.AddSubVal(replacementKey, substitutionValues);
//This replacement key must exist in the message body
replacementKey = "*|MESSAGE|*";
//There should be one value for each recipient in the To list
substitutionValues = new List<string> { "Que día más bueno hace", "ea4t1qj8BnU%3d" };
message.AddSubVal(replacementKey, substitutionValues);
//set the message subject
message.Subject = "Hello World HTML Test";
//create an instance of the SMTP transport mechanism
var transportInstance = SMTP.GetInstance(new NetworkCredential(Username, Password));
//send the mail
transportInstance.Deliver(message);
}
Could anybody please give offer advice on how to avoid this?
Here is the email header after using unicode characters.

By default (and RFC) SMTP headers are US-ASCII. In order to send non-ASCII characters, you need to use Unicode escape sequences. I used the following string and it worked.
Que d\u00EDa m\u00E1s bueno hace
You can find a function in C# to automatically escape those characters for you: Convert a Unicode string to an escaped ASCII string
