What are some best practices for handling fonts and character encoding in PHP when generating graphics on a web server?

When generating graphics on a web server with PHP, it's important to handle fonts and character encoding properly to ensure that text is displayed correctly. To do this, you can specify the font to use and set the character encoding before outputting text onto the image. 

// Set the font and character encoding for text on the image
$font = 'path/to/font.ttf';
$encoding = 'UTF-8';

// Create a new image with specified width and height
$image = imagecreatetruecolor(400, 200);

// Set the background color and text color
$bgColor = imagecolorallocate($image, 255, 255, 255);
$textColor = imagecolorallocate($image, 0, 0, 0);

// Set the font and character encoding for text
imagettftext($image, 20, 0, 10, 50, $textColor, $font, iconv('UTF-8', 'ISO-8859-1', 'Sample Text'));

// Output the image
header('Content-type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);
