Please add a report suite setting to remove all ASCII characters below 32 (non-printable chars) from incoming data.
I cannot think of any need to have them (tabs, linebreaks, bell-signs, ...) in reporting but they currently can break reports, exports and even raw data exports.
Yes, it's not suggested/allowed to have them in the s.xyz variables, but you know...
Advanced solution could be to replace whitespaces (tab, linebreaks) with spaces and remove all other.
