Not enough information was provided for us to be able
to handle this bug. Please re-read the instructions at
http://bugs.php.net/how-to-report.php

If you can provide more information, feel free to add it
to this bug and change the status back to "Open".

Thank you for your interest in PHP.


Need a complete repro script. imap_qprint() requires only a string, not an IMAP server, so you should be able to pare something down.

And keep in mind you can't imap_qprint() an entire multipart email. You have to 
do it to the individual parts (and only the ones that are Quoted-Printable, of 
course).

A lot of people are having problems dealing with malformed quote-printable text.

The malformed q-encoded text from Yahoo:

=?UTF-8?Q?GOG_Forward =?UTF-8?Q?ck-off_with_Weekly_Sale_up_to_90%_off?=

The original q-encoded text that decodes correctly without involving Yahoo for any reason:

=?UTF-8?Q?GOG_Forward=3A_Fw=3A_=F0=9F=98=89_A_great_Monday_kick-?= =?UTF-8?Q?off_with_Weekly_Sale_up_to_90=25_off?=

Both native PHP functions imap_mime_header_decode and quoted_printable_decode throw the error:

Notice: Unknown: Invalid quoted-printable sequence: =?UTF-8?Q?ck-off with Weekly Sale up to 90% off (errflg=3) in Unknown on line 0
