[International / GSM] How to add foreign language dictionaries?

[runelind]

I'm using the rooted 4.1.1 deodexed image from xda which as far as I know is just a rooted version of the stock 4.1.1 image. I'm looking for the ability to add foreign language dictionaries to the keyboard (specifically swedish). Does anyone know how to do this? I've had to temporarily resort to using SwiftKey 3 which does have swedish dictionary support, but I'd like to use the stock JB keyboard if I could.
