Displaying nonprinting characters in libre office calc 3.6.4.3

I’ve searched and searched for it but I cannot figure out if a) it is possible to show nonprinting characters in libre office calc, and b) if it is possible to display npc, how to do it.

Thank you very much for your time.

Check out this Question. It probable has the solution.

I’m sorry, but that solution pertain only to Writer. Tag of this question - Calc. AFAIK in Calc it is impossible :frowning:

Well, it has the solution :wink:Wiki Help · Common · Formatting Aids: “In LibreOffice text and HTML documents, defines the display for certain characters and for the direct cursor.”
