How can the use of html_entity_decode affect the handling of Umlaut characters in PHPExcel?

Using html_entity_decode on Umlaut characters in PHPExcel can cause encoding issues as it converts HTML entities like ä back to their original characters. To properly handle Umlaut characters in PHPExcel, it is recommended to use UTF-8 encoding throughout the process and avoid using html_entity_decode on the cell values. 

// Set UTF-8 encoding for PHPExcel
PHPExcel_Settings::setLocale('de_DE');

// Load your PHPExcel object here

// Loop through cells and output values without html_entity_decode
foreach ($objPHPExcel->getActiveSheet()->getRowIterator() as $row) {
    foreach ($row->getCellIterator() as $cell) {
        echo $cell->getValue() . PHP_EOL;
    }
}
