Cannot get English on keyboard.

I have an older tablet running Kit-Kat version 4 and although it is quite old it is working perfectly well and I recently bought a cover with a bluetooth keyboard built in for it.
I set the language to UK English and although the icon names and system settings show in the correct language the keyboard is outputting what seems to be some sort of arabic language and is printing from right to left on the screen.
I have been through all the settings but try as I might I have been unable to resolve this problem and it is driving me crazy. Am I missing something obvious? any suggestions appreciated.
