Working with Unicode symbols
Updated 21 November 2019
In Calculate Linux, simply hit Caps Lock to switch between the Cyrillic and the Latin (English, by default) keyboard layouts. If the Cyrillic layout is on, the Scroll Lock indicator is on too. To enter additional characters such as currency symbols, fractions, etc., use the Compose key (right Alt Gr). It is called Super in the Xorg jargon.
Below are examples of some Compose key combinations. Press the keys alternately. Cyrillic characters are marked as "(ru)".
