How to add a new keyboard layout to Ubuntu Touch?

Question

I have an Ubuntu Phone and I need a keyboard layout for a language (Romanian) that's not in the list from System Settings / Language & Text / Keyboard layouts.

I would like to contribute with the configuration for the new layout, but I don't know where to start. What files do I need to add or adjust?

Or is there some easier way (like just installing a specific package)?

Answer 1

There is a work in progress page here for creating new layouts, and also there was this thread on the ubuntu-phone mailing list.
