How can the use of PHP arrays and shuffling functions affect the encoding and display of UTF-8 text on webpages?

When using PHP arrays and shuffling functions with UTF-8 text, it's important to ensure that the encoding is handled correctly to prevent any display issues on webpages. One way to solve this is by using the `mb_convert_encoding` function to convert the text to UTF-8 before shuffling the array. This ensures that the text remains properly encoded throughout the process. 

// Sample UTF-8 text
$text = "こんにちは、世界！";

// Convert text to UTF-8 encoding
$text = mb_convert_encoding($text, 'UTF-8', 'auto');

// Split text into an array of characters
$chars = preg_split('//u', $text, -1, PREG_SPLIT_NO_EMPTY);

// Shuffle the array of characters
shuffle($chars);

// Convert shuffled characters back to a string
$shuffled_text = implode('', $chars);

// Display shuffled text
echo $shuffled_text;
