Keyboard Locale stuck in EN_US, system set to EN_GB / UK

[Point & Click]

First: thanks for this application... I use it daily! :)

I'm running this on Arch Linux and the system is setup as "British":

$ localectl status:
   System Locale: LANG=en_GB.UTF-8
       VC Keymap: uk
      X11 Layout: uk

But I can't seem to get Terminator to change from US to UK keyboard... Shift+2 = @, the "#" key = \, etc, etc

I've trawled the documentation and can't seem to see anywhere that this is set / configurable.

This appears to be the same with the bzr version

How can I get this application to match it's environment?

Terminator Version: 1.91
Arch Linux: $ uname -a : Linux archlap 4.18.16-arch1-1-ARCH #1 SMP PREEMPT Sat Oct 20 22:06:45 UTC 2018 x86_64 GNU/Linux

Thanks!
