Our users submit tickets through Outlook e-mail, and there’s a problem that sometimes happen when e-mail is imported into HelpSpot. For some tickets, each apostrophe in the original e-mail is converted to question marks. I know that this apostrophe-into-question-mark problem is not unique to HelpSpot, but I’m trying to figure out the best way of handling this problem in HelpSpot…
Check that your PHP installation has the mbstring library installed. If not the system cannot convert between different character sets which may be the issue.
