Is there a Pac-Man-like character in ASCII or Unicode?
ᗤ <- pacman, also a ghost ᗣ got here by google, someone else will be looking for it, don't remember the unicode for it but i copied the characters from a old file.
I know it's not quite what you asked, but Pacman makes an appearance in the discotastic DF Strand Midnight typeface.
It's not looking good -- presumably, anything resembling Pac-Man would be in the "Geometric Shapes" block, but the closest you'll get is a circle that's 1/4 filled:
