Are there any potential encoding or decoding issues that could be affecting the attachment functionality in Internet Explorer?

The attachment functionality in Internet Explorer may be affected by potential encoding or decoding issues, such as incorrect character sets or encoding formats. To solve this issue, ensure that the encoding and decoding processes for attachments are consistent and compatible with Internet Explorer's requirements. 

// Set the appropriate content type and encoding for the attachment
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="example.txt"');
header('Content-Transfer-Encoding: binary');

// Encode the attachment data using base64 encoding
$attachment_data = 'example attachment data';
$encoded_data = base64_encode($attachment_data);

// Output the encoded attachment data
echo $encoded_data;
