I opened a document in LibreOffice (220.127.116.11) Impress but somehow the special characters are replaced with an envelope sign. The button that should link to "insert special character" is grey and does not work at all. Also "special characters..." in the dropdown menu of "insert" is grey and not working. I just updated Ubuntu 20.04 to 20.10 but I don't use LibreOffice that much so I am not sure if that is linked to the problem.
