How to Detect Which Emoji is Pressed keyboard

Question

I want to use Emoji's in my game But currently unity is not Supporting all Emoji's. So, I decided to Find out that which Emoji is pressed from keyboard, or I can get the Unicode of the Emoji's pressed by keyboard. Is there any way to find that out.

If you want to use emojis (probably in InputField), you first have to download font that supports emojis. You can also get a binary or unicode representation of character. Unity doesn't catch emojis with Input.GetKeyDown, so I suppose you want to do it with InputField. This is how you can do it:

using TMPro;
using System;
using UnityEngine;

public class Test : MonoBehaviour
{
    [SerializeField] private TMP_InputField inputField;

    private void Start()
    {
        inputField.onValidateInput += OnValidateInput;
    }

    private char OnValidateInput(string text, int index, char c)
    {
        print(@$"
binary:  {Convert.ToString(c, 2)};
unicode:  {"\\u" + ((int)c).ToString("X4")};
");

        return c;
    }
}

We just serialize TMP_InputField, where we see what character was written in OnValidateInput event. I hope that helps you!
