That being said, fyi, most Linux distros (or at least many!) have by default the shortcut `ctrl+shift+U` then the hex value of the Unicode character.
So, for example, the en dash is U+2013 and the em dash is U+2014, so you would press `ctrl+shift+U` then type in "2014" then space and it inputs it!
I use it all the time! It's very useful!
