How can PHP developers handle special characters like umlauts in SQL queries?

Special characters like umlauts can be properly handled in SQL queries by using parameterized queries with prepared statements in PHP. This method ensures that the special characters are properly escaped and encoded before being included in the SQL query, preventing any potential SQL injection attacks. 

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare a SQL query with a parameterized statement
$stmt = $pdo->prepare("SELECT * FROM mytable WHERE column_name = :value");

// Bind the parameter value with the special character
$value = "ü";
$stmt->bindParam(':value', $value, PDO::PARAM_STR);

// Execute the query
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll();
