@astromath it doesn't seem like they did. If you look at the Chinese name in the picture, you can clearly see 0 and 1. I think it's just an alt name as of using a female and male symbol.
To me it is clearly the male and female symbols. Especially if it is dealing with genderswap. It only superficially looks like a 0 and a 1. The first symbol is a 0 with a cross on the bottom. The second symbol is a small 0 with a half arrow that looks like a 1. I'm the one that added the alt name because of that.
