You should use double quotes instead. Now you're not matching vertical
tab but \v.

Description:
------------
In preg_match (and preg_replace), vertical tab character matches
characters other than itself. At the least, it matches ascii 10,11,12,13
and 133, when it should only match 11.
(Vertical tab has been nixed from PCRE - is that the cause?)
Reproduce code:
---------------
$wrong = chr(133); //can use any of 10,12,13 or 133
$x = preg_match('/\v/', $wrong, $matches,
PREG_OFFSET_CAPTURE);
var_dump($matches);
$right = chr(11);
$x = preg_match('/\v/', $right, $matches,
PREG_OFFSET_CAPTURE);
var_dump($matches);
Expected result:
----------------
array
empty
array
0 =>
array
0 => string ' ' (length=1)
1 => int 0
Actual result:
--------------
array
0 =>
array
0 => string '�' (length=1)
1 => int 0
array
0 =>
array
0 => string ' ' (length=1)
1 => int 0
