Search with the emoji itself too

[Shawn-sudo]

Before: Typing the emoji itself doesn't show the emoji as a search result

• Example:
  • 
• Typing "👋" won't give "👋" as an option -> not the best user experience

Solution that I'm proposing: modify the search logic a bit to find the emoji that matches exactly

• One problem of my code: It works well for most of the emojis, but there are two or three emojis that doesn't work (❤️ "red heart" is a big one)
