JS Filter emoji emoji

Mobile phone side will often encounter user input box, input emoji, if the database is UTF8, will encounter error: Sqlexception:incorrect string value: ' \xf0\x9f\x98\x84 ' for column ' review ' At row 1

The reason: UTF-8 encoding can be two, three, four bytes. The emoji expression is 4 bytes, while MySQL UTF8 encodes up to 3 bytes, so data cannot be plugged in.
