When using the #new email command, if the message body has any single quote characters (’) the actual message sent to customers is broken and truncated.
For example, if you use:
#new email@example.com Hello, my name is Eric and I'm emailing you from Helpmonk!
What is actually sent to the customer is:
Hello, my name is Eric and I&
I was able to reproduce this 100% of the time. I am unsure if it happens with other special characters.
