Entering special characters in Linux

Occasionally there is a need to enter special characters which are not on the keyboard, for example, an M-dash, ("—") or and N-dash ("–").

This solution works on all recent xorg versions, so it should work on all modern Linux distros.

1. Press Ctr+Shift+U.
2. Release U while still holding Ctr+Shift.
3. Enter the four digit character code, e.g. 2013 for an m-dash, or 2014 for a n-dash.

Some special characters:

Unicode character code (HEX)	Special Character
00a9	©
2013	– (en-dash)
2014	— (em-dash)
20ac	€
20a4	₤
