What are the limitations of using utf8_decode() in PHP when dealing with special characters like the Euro symbol?

When using utf8_decode() in PHP to handle special characters like the Euro symbol, there may be limitations because utf8_decode() only converts UTF-8 encoded text to ISO-8859-1. This means that characters outside of the ISO-8859-1 character set, such as the Euro symbol, may not be properly decoded. To properly handle special characters like the Euro symbol, you can use the mb_convert_encoding() function in PHP with the appropriate encoding parameters. 

$utf8_encoded_text = "Special character: €";
$decoded_text = mb_convert_encoding($utf8_encoded_text, 'ISO-8859-15', 'UTF-8');
echo $decoded_text;
