Exemple de l'utilité de #XCompose : Ce sera facile¹ d'écrire "Happy π day" le 14 Mars.

Ok je sors…

1. Sans se continer les séquences Ctrl + Shift + u + chiffre à la con.

Funny how windoz fanboys are claiming #XCompose "is useless because it's like Alt code but you need to define all the sequences for anything to work..."

You DON'T need to define anything unless your WANT extra characters or to redefine the default sequences... which you don't 95% of the time. There is (obviously) a shitton of default character sequences provided by the OS to begin with (as stated on the tutorial windoz trolls commented)

Not to mention people publishing their own ~/.XCompose
