ERROR 1366 (HY000): Incorrect string value: '\xF0\x9F\x98\x9C' for column 'comment' at row 1

Something in your environment is not set up to correctly process Unicode text.

The byte sequence F0 9F 98 9C, represented incorrectly as "😜" in your query, is the UTF8 encoding of the Unicode character "", FACE WITH STUCK-OUT TONGUE AND WINKING EYE. (That is, it's an emoji character.)

To store this character correctly, you will need to make sure that:

  • You are enabling UTF8 on your MySQL connection (i.e, SET NAMES utf8mb4, or use an option when connecting that similarly enables it).
  • You are running MySQL 5.5 or later.
  • Your table's character set is utf8mb4.

Change connection to mysql from SET NAMES utf8 to SET NAMES utf8mb4


Change connection to mysql from "SET NAMES utf8" to "SET NAMES utf8mb4"

In PHP, use mysqli_set_charset to add charset, https://www.w3schools.com/php/func_mysqli_set_charset.asp

$conn = mysqli_connect("localhost","my_user","my_password","my_db");
if (mysqli_connect_errno()) {
   echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

// Change character set to utf8
mysqli_set_charset($conn, ”utf8mb4”);

Or if you are in NodeJS, (This is extra information, just in case)

db_config = {  
    host: "localhost",
    user: "user",
    password: "password",    
    database: "mydb",  
    charset: "utf8mb4_unicode_ci"
}
var conn = mysql.createConnection(db_config)

Also, make sure the column of the table and the Table itself is of same uf8mb4 encoding.

ALTER TABLE my_table CONVERT TO CHARACTER SET utf8mb4;

ALTER TABLE my_table
   CHANGE COLUMN my_column my_column TEXT
   CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
