Ah yeah, the Unicode Consortium ran into an issue a while back where they realized their emoji descriptors weren’t specific enough and were leading to confusion in cross-platform conversations. Apple used to have a woman in a red dress for “Dancer”, while most Android distributions showed a man in a disco suit. They started getting more specific in their emoji definitions and in 2016 and introduced a few emoji pairs like “Woman Dancing” and “Man Dancing” to clear up the existing confusion.
By 2019 the emoji concepts which were gendered (dancing, etc.) and non-gendered (skiing, surfing, etc.) had become pretty arbitrary. They decided to standardize offering a male, female, and generic version of every human emoji. It’s, you know, a standard, so they generally don’t make that many exceptions. Even emoji like “Santa Claus” have a female “Mrs. Claus” and a generic “Claus” options.
