Both were mapped to empty outlines upstream and are now drawn, so they are no longer blank. They are also the two that most obviously look constructed rather than designed.
¤ U+00A4 currency sign — a ring with four ticks springing from its corners. The ticks read as spiky and do not sit comfortably against the ring at the heavier weights.∑ U+2211 n-ary summation — built from two bars and two diagonal arms. The joins close correctly now, but the result is more angular than a drawn sigma would be.
Neither appears in gravitykit.com content at all, so this is quality rather than function, and low priority.
They are generated in tools/build-symbols.py and tools/build-math.py. Anyone redrawing them should keep the per-face measurement approach the other constructions use, so one shape still serves all seven weights.
