Are there specific PHP functions or settings that need to be adjusted to properly display special characters like umlauts in JSON output from a MySQL database?

Special characters like umlauts may not display correctly in JSON output from a MySQL database if the encoding is not properly set. To ensure that special characters are displayed correctly, you can use the `json_encode()` function in PHP along with setting the appropriate encoding for the database connection and the PHP script. 

// Set the appropriate encoding for the database connection
mysqli_set_charset($connection, 'utf8');

// Fetch data from the database
$result = mysqli_query($connection, "SELECT * FROM table");
$data = mysqli_fetch_all($result, MYSQLI_ASSOC);

// Encode the data to JSON with proper encoding
$json_data = json_encode($data, JSON_UNESCAPED_UNICODE);

// Output the JSON data
echo $json_data;
