Entering Unicode on a Linux system
Press Ctrl, ⇧ (Shift) and U at the same time. Release.
Now enter the hexadecimal code of the desired Unicode symbol. Then press ⏎ (Enter).
For instance in order to enter ≠ (not equal to), press Ctrl⇧U2260⏎ (Enter).
Please note that if Ctrl, ⇧ (Shift) and U has no effect at all, you may miss the package ibus (Intelligent Input Bus), which is an input method framework that allows to easily switch between different keyboard layouts. It also enables the input of Unicode symbols that are not present on the keyboard.
Under Ubuntu and other Debian based distributions the corresponding command would be:
sudo apt install ibusYou may have to execute the command ibus-setup before the first use.
