Valid point about the rendering: I wonder how often Emoji cross-platform rendering causes confusion. (then such confusion leads to something that is presented in court).
Corporations are making these emoji and people are using them to communicate. The meanings are ambiguous, never taught in school, tied to profit motives of domestic or foreign corporations, and liable to change at a moment's notice without all parties receiving the same change. It's a mess for future of society and communication, and that it's showing up in court cases with confusion already is a leading indicator that the problems will get worse.
