    >> It appears you are running into a known issue with creating
       emails with unsupported characters within them. In looking at
       the HTML that came over for this email, I found an instancea of
       a "smart" or "curly" apostrophe. Though it appears similar ( ’
       vs ' ), only the standard apostrophe (the second one) is
       available to be used.

    >> While this should return an error, the known issue is that we
       are creating the email with these special characters
       anyway. This issue has been brought to the attention of our
       engineering and development teams for investigation. The
       workaround at this point is remove any of these unsupported
       characters from the code before submitting.
