What are some common functions or libraries in PHP that can be used to decode special characters, especially those coming from emails?

Special characters in emails, such as those encoded in UTF-8 or quoted-printable format, can be decoded using PHP's built-in functions like `mb_convert_encoding()` or `quoted_printable_decode()`. These functions help convert the encoded characters into their original form, making it easier to display or process the email content. 

// Example of decoding special characters in an email
$emailContent = 'Subject: =?UTF-8?B?U29ycnksIEZvciBJbmZvcm1hdGlvbmFsIFN0dWRlbnQ=?=';
$decodedContent = mb_decode_mimeheader($emailContent);
echo $decodedContent;
