Supporting additional mark-ups that occur when staff copy and paste content into Improvement Module fields

We have found that in reporting into this module (for incidents and complaints) that staff, for the purpose of streamlining entry, generally do a lot of copying and pasting of text. When we then export data to the CSV, which we then provide to a Calumo consultant for importation to a dashboard, there is extensive "hidden or special" characters (not visible in excel) which have to then be stripped using another program. (which is not always successful).
Please see our previously lodged Support Case 00458545 for further detail.
It would be helpful to have this detail stripped upon the exporting of the csv. We think it would be a normal practice that users copy and paste text from various documents/emails all the time when reporting incidents.
