Accents replaced with a strange character in Symfony 6.4 [duplicate]

For 3 days, the characters with French accents no longer appear and are replaced by a �.
Everything was fine before.
In phpmyadmin the display is correct.
It’s only on the remote server, in local all is fine.

In doctrine.yaml there are indeed the indications:

   default_table_options:
                charset: utf8mb4
                collation: utf8mb4_unicode_ci

and in the entities in the header:

#[ORM Table(options: ["collate" => "utf8mb4_unicode_ci", "charset" => "utf8mb4"])]
#[ORM Entity(repositoryClass: Equi‍peadminRepository::class)]

I updated the vendor via composer update.

How to correct this sudden problem?

Thank you for your answers.
Best regards
