What are common pitfalls when decoding emails in PHP?

Common pitfalls when decoding emails in PHP include not properly handling special characters or encoding formats such as UTF-8, ISO-8859-1, or base64. To avoid issues with decoding emails, it is important to use the appropriate PHP functions like `mb_convert_encoding()` or `iconv()` to convert the email content to the desired encoding format. 

// Example of decoding email content using mb_convert_encoding()
$encoded_email_content = "=?UTF-8?B?5Y2O5aW977yM5LiN5LqM?=";
$decoded_email_content = mb_convert_encoding(base64_decode($encoded_email_content), 'UTF-8', 'base64');

echo $decoded_email_content;
