Description:
------------
The mail function cannot send the email has certain characters. For instance the following will not work

$subject = "Joe bloggs edited the Personnel Record of Joe bloggs";

If I strip out the 'd's, it does work:

$subject = "Joe bloggs edite the Personnel Recor of Joe bloggs";

mail("j.bloggs@arts.ac.uk", $subject, "test", "");

My php.ini has the following values:

[mail function]
; For Win32 only.
SMTP = mail.arts.ac.uk

; For Win32 only.
sendmail_from = j.bloggs@arts.ac.uk

The problem also occurs on Linux running PHP Version 4.3.2

Looking in /var/log/maillog:

Sep  1 17:41:57 www-b sendmail[27241]: i81GfvD27241: from=nobody, size=92, class=0, nrcpts=1, msgid=<200409011641.i81GfvD27241@www-b.linst.ac.uk>, relay=nobody@localhost

Reproduce code:
---------------
$subject = "Joe bloggs edited the Personnel Record of Joe bloggs";

subject: 'Joe bloggs edited the Personnel Record of Joe bloggs'

body: 'test'

Actual result:
--------------
