Zero width space (​) in inbound email gets translated to question mark
We are seeing situations where certain versions of Microsoft Outlook insert "​" at the beginning of emails. This is the Unicode Character for ZERO WIDTH SPACE. ServiceNow is translating this character into a question mark which appears at the beginning of the comment.
Steps to Reproduce
1) Log into a madrid patch 10 instance or any other instance's version which suspicions of be facing this issue.
2) Create an email to the instance with the purpose of creating a new incident.
3) Ensure you include this string "​" in the body
4) Inspect the content of the email body and the ticket created and its comment:
ISSUE: You can notice "​" is being translated into a question mark:
<p>​ line one.<br>
Incident update to:
?This is line one.
This is line two.
