Unicode is a crazy thing♙♙♙ the tough guy's ASCII. I loved the idea since the start, although it has always been clear to me that it would be a broken system, full of frustrations.
It actually works better than you would think. And then you can have fun putting some 👩 or ⛑ or ♛ ♘ ⛔ ☭ ☠ � etc, etc. in what one likes the most of a computer: plain text.
To enter a Unicode character of which you knows the code, in Linux, got ctrl+shift+U and the code itself.
E.g., ctrl+shift+0239 gives you... ȹ.
