Discussion Message Cut off

I have Elgg 2.3.6 running on my website.

An issue: My users received email notifications from their group's posts and replied to the post via an email using iOS device. We noticed that the responses were cut off when there are 'Smart Quotes' in the response body. Smart quotes include 'single quotes', 'double quotes', and 'apostrophe'. We have been trying to replicate what the users did using the similar iOS device and email client but we cannot replicate the issue they have.

Question: Has anyone encountered this issue before? Any thoughts or advices on this issue?

Greatly appreciate your help or inputs!
