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. In particular, I will never forgive them for having excluded the subscript b (and others [1]).
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, in many applications go for ctrl+shift+U and the code itself.
E.g., ctrl+shift+U+0239 gives you... ȹ.
In Emacs, C-x 8 RET.
In html, ode; produces the character, .e.g., = for instance, produces = which could be useful as the actual = could break a template (such as the cite one).
In Mediawiki, {{unicode|&#code;}} could be used.
