Are there any specific PHP functions or methods that can help with handling UTF-8 characters in form processing?

When processing form data in PHP that contains UTF-8 characters, it's important to handle these characters properly to avoid encoding issues. One way to do this is by using PHP functions like mb_convert_encoding() and mb_strlen() to work with UTF-8 strings. These functions allow you to convert the encoding of strings and calculate the length of UTF-8 characters accurately. 

// Example of using mb_convert_encoding() and mb_strlen() to handle UTF-8 characters in form processing

// Convert the input string to UTF-8 encoding
$input = $_POST['input'];
$input_utf8 = mb_convert_encoding($input, 'UTF-8');

// Get the length of the UTF-8 string
$length = mb_strlen($input_utf8);

echo "UTF-8 input: " . $input_utf8 . "<br>";
echo "Length of UTF-8 input: " . $length;
