Custom .XCompose

[Xen]

So apparently there is a guy who has tried to mimic the Windows 
behaviour as closely as possible.

There is a .XCompose you can download that will (or should) fix all of 
those dead accent issues with 'n and 'r.

It's just that it doesn't work for me and my .XCompose is not even read 
by the system.


So first question:



How do you get the .XCompose read by the system, using either:


- fcitx
- xim
- uim

as input method?

Does /usr/share/X11/locale/en_US.UTF-8/Compose even get read by the 
system? I don't know...

Last access an hour ago. It is clearly not getting read...

My LANG is en_US.UTF-8 and LC_CTYPE is the same....

What woodwork do I find myself into this time...
