There might be a loose standard, but if you've ever tried to reliably convert text with emojis to a static image or print media (with proper licensing), you've probably experienced how much of a pain they can be. The fact that new emojis keep getting added to the standard means that at any point in time, your implementation (font/code/assets) might be out out-of-date and sprinkled with tofu. It's a constant battle — one that even Apple can't seem to keep up with on their own platforms (I'm looking at you, Messages app in MacOS Sierra).
