 New Comment:

We have (if I counted right) 3 different implementations for
encoding/decoding quoted-printable. And unfortunately filters.c has the
buggy one which requires the encoded hex chars be upper-case, since this
works:

<?php

$foo = "Sauvegarder=C3=A9ussi(e)";
// $foo = "Sauvegarder=c3=a9ussi(e)"; // Does not work!
$b = fopen('php://temp', 'w+');
stream_filter_append($b, 'convert.quoted-printable-decode',
STREAM_FILTER_WRITE);
fwrite($b, $foo);
rewind($b);
fpassthru($b);

?>

Description:
------------
Using the quoted-printable-decode filter on a stream produces an error.
 However, decoding the string using quoted_printable_decode() does not
fail.

The error is thrown whether stream_filter_append() is used or a while
!feof()/fwrite()/fread() loop is used.

Reproduce code:
---------------
$a = fopen('php://temp', 'r+');
fwrite($a, "SERVER: [ID job :3453 Backup rotation] Sauvegarde
r=c3=a9ussi(e)");
rewind($a);

$b = fopen('php://temp', 'r+');
$c = stream_filter_append($b, 'convert.quoted-printable-decode',
STREAM_FILTER_WRITE);
stream_copy_to_stream($a, $b);
rewind($b);
fpassthru($b);
stream_filter_remove($c);

rewind($a);
rewind($b);
fwrite($b, quoted_printable_decode(stream_get_contents($a)));
rewind($b);
fpassthru($b);


Expected result:
----------------
SERVER: [ID job :3453 Backup rotation] Sauvegarde réussi(e)
SERVER: [ID job :3453 Backup rotation] Sauvegarde réussi(e)

Actual result:
--------------
PHP Warning:  stream_copy_to_stream(): stream filter
(convert.quoted-printable-decode): invalid byte sequence in
/tmp/test.php on line 8
SERVER: [ID job :3453 Backup rotation] Sauvegarde réussi(e)
