What is the significance of using UTF-8 consistently in PHP applications, especially when dealing with database connections?

Using UTF-8 consistently in PHP applications is important because it ensures that data is stored and retrieved correctly, especially when dealing with special characters and multilingual content. When connecting to a database, it is crucial to set the character encoding to UTF-8 to avoid issues with data corruption or display problems. 

// Set UTF-8 encoding for database connection
$dsn = 'mysql:host=localhost;dbname=my_database;charset=utf8';
$username = 'username';
$password = 'password';

try {
    $pdo = new PDO($dsn, $username, $password);
    $pdo->exec("set names utf8");
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();
}
