如何轉換此二進制字符串：b"iphonée@3,;= ???e x"到普通字符串？我真的需要將該字符串作為普通字符串，而不是作為二進制字符串。我在 MySQL 中保存這個二進制字符串時遇到問題。如果我解碼的 CSV 沒有 ?、é 或任何這些非常規字符，則保存沒有問題。但是，當在單元格上設置其中一個字符時，該字符串似乎是二進制字符串，并且在 MySQL 上保存此二進制字符串時出現錯誤。我收到此錯誤：QueryException {#1780  #sql: "insert into `seller_product_languages` (`seller_product_id`, `lang`, `name`, `description`, `description_html`, `bullet_html`, `bullet`, `meta_keywords`, `default`, `updated_at`, `created_at`) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"  #bindings: array:11 [    0 => 117    1 => "es"    2 => b"iphonée@3,;= ???e x"    3 => "negro"    4 => "negro"    5 => null    6 => ""    7 => null    8 => 1    9 => "2020-03-02 18:40:56"    10 => "2020-03-02 18:40:56"  ]  #message: b"SQLSTATE[HY000]: General error: 1366 Incorrect string value: '\xE9e@3,;...' for column 'name' at row 1 (SQL: insert into `seller_product_languages` (`seller_product_id`, `lang`, `name`, `description`, `description_html`, `bullet_html`, `bullet`, `meta_keywords`, `default`, `updated_at`, `created_at`) values (117, es, iphonée@3,;= ???e x, negro, negro, , , , 1, 2020-03-02 18:40:56, 2020-03-02 18:40:56))"  #code: "HY000"  #file: "/home/vagrant/Code/PROJECT/vendor/laravel/framework/src/Illuminate/Database/Connection.php"  #line: 664  -previous: PDOException {#1779    #message: "SQLSTATE[HY000]: General error: 1366 Incorrect string value: '\xE9e@3,;...' for column 'name' at row 1"    #code: "HY000"    #file: "/home/vagrant/Code/PROJECT/vendor/laravel/framework/src/Illuminate/Database/Connection.php"    #line: 458    +errorInfo: array:3 [      0 => "HY000"      1 => 1366      2 => "Incorrect string value: '\xE9e@3,;...' for column 'name' at row 1"    ]所有表和列都是'utf8mb4'和排序規則'utf8mb4_unicode_ci'環境：-PHP 7.2 -Laravel 5.5 -Ubuntu 18.04 -MySQL 5.7
