No, the regular expression was changed in order to support UTF-8
strings. Note the "u" modifier and the UTF-8 property checks ("L" for
letter, "N" for number).

Hmm, interesting. It appears that on this system the UTF-8 support is
not available.

No, I have been unable to reproduce the problem through unit testing on
the following platforms:
* PHP 5.1.4, WinXP, PCRE 6.6
* PHP 5.2.1, Ubuntu, PCRE 6.7

Thank you for posting these results. It appears that we need some more
investigation to find the root cause of the problem... calling all
volunteers!
