IMO it's a huge mistake to make Unicode a repository of random clip art. Of course that ship has sailed and if there is a taco character then someone will complain that there isn't a lasagna character and a broccoli chicken character, and those will be added as well, until the entire character space is full of clip art. And each person that got their favorite variety of cupcake or flavor of ice cream included or the addition of a unique character for gluten free vegan lasagna will proudly add to their resumé that they have contributed to the Unicode standard.
