What are the best practices for encoding and decoding XML data in PHP to ensure proper handling of character encoding?

When encoding and decoding XML data in PHP, it is important to ensure that the character encoding is handled properly to avoid data corruption or loss of information. To ensure proper handling of character encoding, it is recommended to use the `utf8_encode()` function when encoding data to XML and the `utf8_decode()` function when decoding XML data. 

// Encoding data to XML with proper character encoding
$data = utf8_encode($data);
$xml = new SimpleXMLElement('<root></root>');
array_walk_recursive($data, array ($xml, 'addChild'));

// Decoding XML data with proper character encoding
$xmlString = $xml->asXML();
$decodedData = utf8_decode($xmlString);
