How set UTF-8 in PDO class constructor for PHP PgSQL database

Question

I want to set UTF8 for my PDO object. This class works correctly with MySQL. I can\'t find an analog of array(PDO::MYSQL_ATTR_INIT_COMMAND => \"SET NAMES UTF8\")

Answer 1

it is very easy to find an analog for the regular SQL query

$pdo->query("SET NAMES UTF8")

However, encoding have to be set in DSN anyway

$this->conn = new PDO("pgsql:host=".$this->host.";dbname=".$this->db.";charset=".$this->charset
