What role does the utf8_encode() function play in converting character encoding in PHP, and when should it be used?

The utf8_encode() function in PHP is used to convert a string from ISO-8859-1 encoding to UTF-8 encoding. This function is useful when you have a string that is encoded in ISO-8859-1 and you need to convert it to UTF-8 to ensure proper handling of international characters. It should be used when you encounter encoding issues with special characters in your PHP application. 

// Example of using utf8_encode() function to convert ISO-8859-1 encoded string to UTF-8
$iso_string = "Café"; // String encoded in ISO-8859-1
$utf8_string = utf8_encode($iso_string); // Convert to UTF-8

echo $utf8_string; // Output: Café
