For Demestvenny notation, the seldom-used sequence of Skameitsa klyuchevaya (U+1CF75) plus Slozhitie (U+1CF7D) forms a ligature that cannot be conveniently produced by kerning, as the amount of kerning would be excessive and the anchor points would be problematic. I propose that we add a lookup to point to a newly-added composite (or contracted) character at U+EC11.
