How can multibyte characters affect the accuracy of character counting in PHP?

Multibyte characters can affect the accuracy of character counting in PHP because they require more than one byte to represent a single character. This can lead to incorrect character counts if not handled properly. To accurately count multibyte characters in PHP, you can use the `mb_strlen()` function instead of `strlen()`. 

$string = "こんにちは"; // Japanese greeting with 5 characters
$characterCount = mb_strlen($string, 'UTF-8'); // Use mb_strlen() to accurately count multibyte characters
echo $characterCount; // Output: 5
