如何在MySQL数据库中插入4个字节的unicode字符？

Question

I'm occasionally getting following exception when someone tries to insert smiley into my database:

Incorrect string value: '\\xF0\\x9F\\x98\\x8A' for column 'name' at row 1

The name is defined as

`name` VARCHAR(255) CHARACTER SET utf32 COLLATE utf32_general_ci NOT NULL,`

And I'm using CharSet=utf8; in my connection string

What else should I check/change for full unicode insert to start working?

Answer 1

you have to change your collation of database table to utf8mb4_bin

And set CHARACTER SET in database configuration as utf8mb4
