When I'm logged as user or root I cannot type the letter d on a terminal, and if I paste a word containing it the d is erased.

I can type it in the graphical interface (i3wm) and in non-graphical terminals, the last only before I log as user or root.

I'm on Manjaro 17.06 i3 Community Edition.

Update: d works fine on zsh.

Try entering the 'd' key with Alt+100 on the numeric keypad, and use it to run the dumpkeys command:

dumpkeys -1 --keys-only | grep e..32 | head -n 1

In alternative you can try

$( echo DUMPKEYS | tr "[A-Z]" "[a-z]" ) -1 --keys-only | grep e..32 | head -n 1

to do the same thing without typing a lowercase d.
It should report that plain keycode 32 maps to "+d". Otherwise you've got a funny loadkeys command somewhere, probably (but not surely) under /etc, in the user loaded commands (e.g. /etc/bash.bashrc or similar).

Seeing as this is the first character of your name, I would not rule out a prank.
