#48790 [NEW]: Unicode character properties misbehave

From:             php at pwnt dot be
Operating system: Windows XP SP3
PHP version:      5.2.10

Bug description:  Unicode character properties misbehave

Description:
------------
The behavior described at
http://php.net/manual/en/regexp.reference.unicode.php seems to have changed
between PHP 5.2.8 and 5.2.10 (don't know about 5.2.9). I use preg_match()
with a \p regexp to check if a character is a letter (or a number, in this
case), and this seems to fail for wide characters in 5.2.10.

Reproduce code:
---------------
echo preg_match('/^[\pL\pN]$/', 'é');

Expected result:
----------------
1

Actual result:
--------------
PHP 5.2.8: 1
PHP 5.2.10: 0
