Since I have created a blueprint for Ruble sign glyph in Ubuntu-Font I guess its addition to the Ubuntu-keyboard can wait (maybe a separate bug or a feature request will do). The semantic differences fixed at this point are quite important for many functions such as searching so this should be merged with Ubuntu-keyboard ASAP. Just updating this to bring some visibility.
