Did you take a look at Mister_e's work on the "Using Nokia LCD" by chance?
I have looked but its chief issue for me is the way the font is stored/retrieved ,for a pic16 with limited resources
its just too inefficient. if it ports to the method I used for the ssd1306 controller then it will be a better result.
not only that imho usercommand [a sadly underused feature ] makes nicer code
