Emoji snapshot methods

[nedtwigg]

We will never ship this by default, but it might make sense to do something like what blowdryer did for 干

• com.diffplug.selfie:selfie-kotlin-emoji
  • expectSelfie -> 🔎
  • this would only work in kotlin, and it would have to be bracketed with double-backticks, but it stands out visually
  • Unicode has both 🔎 and 🔍, doesn't really matter which, but we should not do both and :mag_right: works in GitHub but :mag_left: doesn't so that's the tiebreaker
  • another option is expectSelfie -> 📷
• com.diffplug.selfie:selfie-ku
  • expectSelfie -> 𐌒
  • this is using the old italic letter ku, which would work in java and kotlin

The code would look something like this

object 𐌒 {
  @JvmStatic fun 𐌒(actual: String) = Selfie.expectSelfie(actual)
  @JvmStatic fun 𐌒(actual: Int) = Selfie.expectSelfie(actual)
  @JvmStatic fun 𐌒(actual: Boolean) = Selfie.expectSelfie(actual)
}

It's cute, but it's very easy for people to do themselves in their own projects, and it's probably a bad idea so we shouldn't encourage it by publishing artifacts for it.

The 🔎 has a tiny sliver of functionality, the color does standout just a bit, seems appropriate.
