Bug #47868 [Opn->Nab]: Special apostrophe character stripped from subject

Edit report at https://bugs.php.net/bug.php?id=47868&edit=1 ID: 47868 Updated by: requinix@php.net Reported by: cconnors at online-buddies dot com Summary: Special apostrophe character stripped from subject -Status: Open +Status: Not a bug Type: Bug Package: Mail related Operating System: win32 only - XPSP2 PHP Version: 5.2.9 Block user comment: N Private report: N New Comment: The Wayback Machine has an archived copy with the description. https://web.archive.org/web/20120723104144/https://bugs.php.net/bug.php?id=47868 mail() doesn't know what encoding the string you gave for the subject is so stripping out bytes that aren't allowed in 7-bit ASCII is IMO a fair resolution. You can easily encode the subject yourself with "=?iso-8859-1?Q?" . quoted_printable_encode("french d\x92avoir") . "?=" (if it's ISO-8859-1 encoding, otherwise you'll need a different string) The relevant RFC is 2047 http://www.ietf.org/rfc/rfc2047.txt Or, you know, use a mail library that does all this stuff for you.

The header field must be encoded if you want non-ASCII characters in it, as in: Subject: =?iso-8859-1?Q?french d=92avoir?= ------------------------------------------------------------------------ [2009-04-01 21:30:37] cconnors at online-buddies dot com Description: ------------ The following character (’) is automatically stripped from a subject, but not the body using mail(). Quick fix is... $subj = str_replace('’', '\'', $template->getSubject()); But it's not EXACTLY the same character. I've played around with the header, and cannot get it to work with UTF-8. Reproduce code: --------------- header = "From: ". 'noreply' . " <" . 'noreply@foo.net' . ">\n" . "Reply-To: " . 'noreply@foo.net' . "\n" . "Content-type: text/plain; charset=UTF-8\n\n"; mail('fake@foo.net', 'french d’avoir' , 'french d’avoir', $header); Expected result: ---------------- Should get a message with: subject: french d’avoir body: french d’avoir Actual result: -------------- Actually get: subject: french davoir body: french d’avoir ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=47868&edit=1
