I don't have PHP 6 compiled at hand, but I assume that PHP 6 is
replacing the bad char before sending the string to pcre.
Can you check if it's the case by printing $str?

Nuno, how come the script says "match" with HEAD?

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

Check preg_last_error() it will return PREG_BAD_UTF8_ERROR

\xab isn't valid UTF-8, however \xc2\xab is. It should be 2 bytes.

Works in HEAD.

$str is not a valid UTF-8 string, and thus the pcre engine rejects it.
no bug here.

Description:
------------
preg_match() doesn't match string when utf-8 mode is enabled and 0xAB
char ("«") is present in input. Everything works correctly when
utf-8 mode is disabled.

Reproduce code:
---------------
<?php

$str = "test \xab test";

if (preg_match('/test/u', $str))
	echo 'Match';
else
	echo 'No match';

?>

Expected result:
----------------
'Match' printed

Actual result:
--------------
'No match' printed


------------------------------------------------------------------------
