If you're bellyaching about emojis, you should be treating them as a litmus test: If your application can't handle emojis, it's because you're doing something you're not supposed to (specifically, making false assumption about the nature of text), and thus you will run into situations with text that break your shit, too.

The way I see it, emojis are practically single-handedly responsible for near-universal adoption of Unicode in the Anglosphere. Otherwise, it would be all too easy for lazy developers to just use ASCII and then shove their fingers in their ears about any other writing systems.
