Notas

Nota:

MySQLnd sempre assume o charset padrão do banco de dados. Este charset é enviado durante a criação da conexão, e o mysqlnd usará a partir daí.

Libmysql utiliza o charset padrão configurado no arquivo my.cnf ou por uma chamada a mysqli_options() anterior a chamada de mysqli_real_connect() e depois de mysqli_init().
