确保在数据库配置文件中正确设置了字符集和排序规则。

// config/database.php
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', ''),
'username' => env('DB_USERNAME', ''),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_general_ci',
'prefix' => '',
'strict' => false,
'engine' => null,
],

这将使 laravel 知道保存时要使用什么utf8mb4字符集
