can't type the caret ^ symbol
In gnome terminal, under ubuntu 18.04, I can't type the caret ^ symbol, which instead works on all other applications (firefox, chrome, libreoffice, guake, terminator etc). My system language is US English, while my keyboard layout is italian (italian no dead keys has the same problem). This is quite problematic since I use vim all the time. I've tried to change the terminal fonts but it makes no difference.
