I'm trying to get a font, SambhotaUnicode, to align on the ascender line, so that text reads evenly across the heads of the letters at different sizes. Another font, TibetanMachineUnicode, actually does this just fine. However I'm not sure why or where to start digging to update SambhotaUnicode to match the latter's beavhour. Using fontforge's tools to do a diff it does say there are different truetype instructions.
SambhotaUnicode (left, incorrect) vs. TibetanMachineUnicode (right, correct):
For context, I'm using LaTeX, and there are other limitations in it arround wrapping long blocks of text in boxes, hence it seems like adjusting the font might be the simplest and seemingly the most correct way to fix it.
