What are the best practices for handling UTF-8 characters when using str_replace in PHP?

When using `str_replace` in PHP with UTF-8 characters, it's important to ensure that the function handles multi-byte characters correctly. To do this, you should use the `mb_` functions in PHP, such as `mb_str_replace`, which are specifically designed to work with multi-byte character encodings like UTF-8. 

// Example of using mb_str_replace to handle UTF-8 characters
$text = "Héllo wórld";
$find = "é";
$replace = "e";

$result = mb_str_replace($find, $replace, $text);

echo $result; // Output: Hello world
