What role does mbstring() play in handling UTF-8 characters in PHP output?

When working with UTF-8 characters in PHP output, the mbstring extension is crucial for handling multibyte character encoding properly. It provides functions for working with multibyte strings, such as detecting character encoding, converting between different encodings, and performing string operations that account for multibyte characters. By using mbstring functions, you can ensure that your PHP application correctly processes and displays UTF-8 characters. 

// Ensure that mbstring extension is enabled
if (!extension_loaded('mbstring')) {
    die('The mbstring extension is required for handling UTF-8 characters.');
}

// Set internal encoding to UTF-8
mb_internal_encoding('UTF-8');

// Example of using mbstring functions to work with UTF-8 characters
$text = "こんにちは"; // Japanese greeting
echo mb_strlen($text); // Output: 5
echo mb_substr($text, 0, 3); // Output: こん
