This is a symbol for female or woman with a point of light added at each corner of the character area. Each corner represents a cardinal direction, and a point of light signifies that something is true. In other words, everywhere is female. Thus, this is an ideograph for women only.

Comment:
This is Mahadevan's sign number 8025, which I have reversed to reflect the actual Indus sign used in inscriptions H-945 and H-946.
Tablets H-945 and H-946 are tokens for return journeys by private hire vehicle. Each tablet gives the approximate distance to be travelled, and states women only.
