What role does the gd-lib play in handling Umlauts in ImageTTFText in PHP?

The gd-lib library in PHP plays a crucial role in handling Umlauts (special characters like ä, ö, ü) when using the ImageTTFText function. Without gd-lib, these characters may not be rendered correctly in the generated image. To ensure proper handling of Umlauts, make sure that gd-lib is installed and enabled in your PHP environment. 

// Check if gd-lib is enabled
if (!function_exists('gd_info')) {
    die('GD library is not enabled');
}
