How can the exact encoding of input data be determined in PHP to ensure proper handling of special characters?

When dealing with input data in PHP, it is important to determine the exact encoding of the data to ensure proper handling of special characters. One way to do this is by using the `mb_detect_encoding()` function in PHP, which can help identify the encoding of the input data. Once the encoding is determined, you can then use functions like `mb_convert_encoding()` to convert the data to the desired encoding for consistent handling of special characters. 

$input_data = "Some input data with special characters";
$encoding = mb_detect_encoding($input_data);
if($encoding != 'UTF-8'){
    $input_data = mb_convert_encoding($input_data, 'UTF-8', $encoding);
}
// Now $input_data is in UTF-8 encoding for proper handling of special characters
