Are there specific PHP functions or libraries that can assist in properly displaying kyrillische Zeichen on a website?

To properly display Cyrillic characters on a website using PHP, you can use the `mb_convert_encoding` function to convert the text to UTF-8 encoding. This ensures that the characters are displayed correctly across different browsers and platforms.

// Convert Cyrillic characters to UTF-8 encoding
$text = "Кириллические символы";
$utf8_text = mb_convert_encoding($text, 'UTF-8', 'ISO-8859-5');

echo $utf8_text;
