Answer 1

maybe you can take a look of this article: http://crocodillon.com/blog/parsing-emoji-unicode-in-javascript

the emoji unicode from \u1F601 to \u1F64F

translate to javascript's utf-16 is \ud83d\ude00 to \ud83d\ude4f

the first char is always \ud83d.

so the reg is out:

/\ud83d[\ude00-\ude4f]/g

hope this can make some help
