Nodejs,javascript filter Emoj expression

1 Preface

Since the nickname with Emoj expression cannot be stored in MySQL character_set_server= UTF8 mode, the reference article [1], changed to UTF8MB4, invalid (may use the wrong method).

The general idea is to filter the nickname Emoj expression, get filtered nickname.
