What are the best practices for handling UTF-8 encoding when working with XML files in PHP?

When working with XML files in PHP, it is important to handle UTF-8 encoding properly to ensure that special characters are correctly represented. One way to do this is by setting the encoding of the XML document to UTF-8 and using functions like utf8_encode() and utf8_decode() when necessary. 

// Set the encoding of the XML document to UTF-8
$xml = new DOMDocument('1.0', 'UTF-8');

// Use utf8_encode() to encode strings to UTF-8
$encodedString = utf8_encode($originalString);

// Use utf8_decode() to decode UTF-8 strings
$decodedString = utf8_decode($utf8String);
