PHP: How To Save Binary String In MySQL 5.7

How can I convert this binary string:

b"iphoné[email protected],;= ÑÑñe x"

To normal string?

I really need to have that string as a normal string, and not as a binary string.

I am having problems saving in MySQL this binary string. If the CSV that I decode does not have ñ, é or any of this non usual characters, I dont have problem saving. But when one of this characters is set on a cell, the string appears to be binary string and I get an error when saving on MySQL this binary string.

I get this error:

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 (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"

    ]

All tables and columns are 'utf8mb4' and collation 'utf8mb4_unicode_ci'

Environment: -PHP 7.2 -Laravel 5.5 -Ubuntu 18.04 -MySQL 5.7

Answer

I solve it changing all tables from utf8 to utf8mb4. And doing utf8_encode(..) to the string

Thank you all
