The character in the costume was "Old Man Smithers," a typical villain like the ones in the old Cartoons. It could have been a woman, but the part called for carrying Daphne Blake under one arm while engaging in combat. Some women are that strong, but the typical upper body strength of males makes it more plausible for a man to be the Luna Ghost. Originally he was going to be the master villain of the whole movie, the demon summoner (until they decided to make it Scrappy-Doo instead).
Perhaps the questioner is thinking of Luna of the Hex Girls, who first appeared in "Scooby-Doo and the Witch's Ghost." That character is female, but she has no connection to the Luna Ghost at all.

The Luna Ghost is a new character for "Scooby-Doo" the live-action movie, and was never a character on the TV series. Since Old Man Smithers was dressed as the ghost in the movie, no woman has dressed up as the Luna Ghost before.

I believe you're thinking of Spirited Away.
There is a ghost hunter near the Inn on Ghost Story island (you get his binoculars when he's led away). Once you have gone into the old house and met the old woman named Fiona, you can receive your ghost-hunting equipment from Jane, the woman at the bakery.

The weeping woman (Spanish: La Llorona)
It may not mean anything significant to see a ghost of a person that is not known. It may also mean that this ghost has a message for the viewer.
