How can the issue of Umlauts being displayed as question marks (�) when including an external TXT file be prevented in PHP?

The issue of Umlauts being displayed as question marks (�) when including an external TXT file in PHP can be prevented by ensuring that the file is read with the correct encoding. You can specify the encoding when reading the file using functions like `file_get_contents()` or `fopen()`. 

$file = 'external_file.txt';
$content = file_get_contents($file, false, null, -1, 10000); // Specify encoding if needed
echo $content;
