Hi,

I've been building a simple ticket system and it's all done and working except for when it receives PDF files via email that have been sent using quoted-printable encoding. I've tried using quoted_printable_decode(), the quoted-printable.decode stream filter, the later just created an empty file. I've also tried using $input = preg_replace('/=([a-f0-9]{2})/ie', "chr(hexdec('\\1'))", $input).

However the PDF file is always unreadable. I've compared the original with the rebuilt version and there are a lot of 00 missing and some other characters replaced.
