If you want to store Emoji characters in a MySQL DB, you need to update the table encoding. You can do this by…
ALTER DATABASE <DATABASE_NAME> CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci ;
ALTER TABLE <table_name> CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
-- ALTER TABLE <table_name> MODIFY <field_name> TEXT CHARSET utf8mb4;
