A team of Google employees proposed a set of 13 professional women emoji to the Unicode Consortium. With this collection their goal is to: “highlight the diversity of women's careers and empowering girls everywhere”. The symbols are created in a rebus-like way. For example the nurse is created by a combination of a woman emoji and a hospital emoji. With this method, it can easily change in a man figure. The team wants to get the new emoji standardized by the end of 2016. There’s a big chance they will succeed, because one member of the team Mark Davis is also co-founder of the Unicode Consortium.
Unless I think this method is a very cool way to create many variations, it also becomes more complicated. With the limitation of available pictograms, I think a better way to keep all users satisfied is to simply make them look less human-like. Unfortunately, this is the opposite of Google’s current strategy.
