Description:
------------
When using the following test script to strip out all unicode except for
letters the string becomes garbled when the * qualifier is added, the
only surviving character that is intact is ú.



Also, if you add \pN to the exceptions it additionally preserves the
ó.



Verified on 5.2,5.3 and 5.3-SNAP.



Test script:
---------------
echo preg_replace('/[^\pL\pM]*/iu', '', 'áéíóú');

or

echo preg_replace('/[^\pL\pM\pN]*/iu', '', 'áéíóú');

Expected result:
----------------
áéíóú

Actual result:
--------------
����ú

or 

���óú (if \pN is added to the exceptions).
