Description

I am trying to get smileys through keyValue of onKeyPress attribute of TextInput.

Expected output: I get the pressed smiley
Actual output: I don't get 97% of pressed smiley

Note: I tried the same with latest react native version, still it exists

Reproducible Demo

If you run this code and try to input smileys through the keyboard in phone, you won't be alerted most of the smileys.

`import React from 'react'
import { View, TextInput } from 'react-native'

export default class TextInputCheck extends React.Component {

_onKeyPress = ({ nativeEvent: { key: keyValue } }) => {
    alert('Pressed: ' + keyValue)
}

render() {
            return (
                <View style={{flex: 1, justifyContent:'center',alignItems: 'center'}}>
                    <TextInput
                        onKeyPress={this._onKeyPress}
                    />
                </View>
            )
}

}
`
