Recurring Error on Comment Response Workflows - Return Key/Essay Text Box

We're seeing periodic comment response failures on a couple of our surveys ever since we updated our comment response format from single line to essay text box. We've determined that the failure might be caused by some respondents using the Return key in their comments; when they do this, it appears to insert " /n " which may be causing the workflow to fail. Is there any means of preventing and/or correcting this issue in Qualtrics? Thank you!
