How can the mb_convert_encoding function in PHP be used to handle character encoding issues when reading files?

When reading files in PHP, character encoding issues may arise if the file is encoded in a different format than expected. To handle this, the `mb_convert_encoding` function can be used to convert the file's encoding to the desired format before processing it further. 

// Read the file contents
$file_contents = file_get_contents('example.txt');

// Convert the encoding to UTF-8
$file_contents = mb_convert_encoding($file_contents, 'UTF-8', 'auto');

// Process the file contents
// (e.g., echo or save to a database)
echo $file_contents;
