What potential encoding issues should be considered when generating HTML code from an XML file using xslt_process() in PHP?

When generating HTML code from an XML file using xslt_process() in PHP, potential encoding issues to consider include ensuring that the XML file and the XSL stylesheet are encoded in the same character encoding, such as UTF-8, to avoid garbled output. Additionally, it is important to properly set the encoding in the output HTML header to match the character encoding used in the XML and XSL files. This can be done by specifying the encoding attribute in the xsl:output element in the XSL stylesheet. 

// Load the XML file
$xml = new DOMDocument();
$xml->load('input.xml');

// Load the XSL stylesheet
$xsl = new DOMDocument();
$xsl->load('stylesheet.xsl');

// Create a new XSLT processor
$proc = new XSLTProcessor();

// Import the XSL stylesheet
$proc->importStylesheet($xsl);

// Set the output encoding in the XSL stylesheet
$xsl->getElementsByTagName('output')->item(0)->setAttribute('encoding', 'UTF-8');

// Transform the XML using the XSL stylesheet
$html = $proc->transformToXML($xml);

// Output the HTML
echo $html;
