I'm not sure that the `v` flag introduced in JS's regulars helps, in the case of emoji, which contains the following type field:

- Basic_Emoji
- Emoji_Keycap_Sequence
- RGI_Emoji_Modifier_Sequence
- RGI_Emoji_Flag_Sequence
- RGI_Emoji_Tag_Sequence
- RGI_Emoji_ZWJ_Sequence
- RGI_Emoji

See: 
- https://v8.dev/features/regexp-v-flag
- https://unicode.org/Public/emoji/16.0/emoji-sequences.txt

```js
/^\p{Emoji}$/v.test('👨‍❤️‍👨')
// → false ❌

/^\p{RGI_Emoji}$/v.test('👨‍❤️‍👨')
// → true ✅
```
