Thanks for reaching out to us! I took a look at your latest email and tried to copy and save a draft to recreate the message you saw, but I was not able to. I apologize that I can't tell what the unsupported character was from the copied text. I do see that the email sent successfully, so I hope the issue was resolved without too much trouble. If you run into this issue in the future and need help identifying the character please don't hesitate to give us a call so that we can troubleshoot with you immediately.
