Make sure to add this line of code to your program's startup logic:

System.Text.Encoding.RegisterProvider (System.Text.CodePagesEncodingProvider.Instance);

Then, when authenticating to your SMTP server, use the Authenticate() method that allows you to pass a System.Text.Encoding parameter to tell MailKit which encoding to use when encoding your password.
