Re: A criteria for Emoji property assignment?

3. In the Geometric Shapes block, only two characters (25AA ▪ and 25AB ▫) are considered emojis, while other 94 aren’t. While did just these two little squares deserve the honor of bearing Emoji property, in contrast to all other geometric shapes?

My phone renders all emojis as (25AA ▪ ) except for those off the BMP, which it renders as ▪▪.

Judging from context, the single ones would most likely be the smiley face, so that's OK; any complicated string of ▪▪ would most likely just be as obscure a message to me if it were rendered in pictures.
