We have an issue where an email sent from a journey is rendered with '????????' instead of Hebrew letters. We examine the mime code header (within the .eml file) and found this:
Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: 7bit
This can explain why the Hebrew letters rendered as '????????'. Then we copied the email in email studio and send it again. This time the Hebrew characters rendered well and the mime code header looks like this:
Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: 8bit
The question is what determines the encoding Marketing Cloud set to the message? In this case both messages are identical and MC sends them with different encoding each time.
Thanks a lot, Barak
