Bug #48790 Unicode character properties misbehave
Submitted: 2009-07-03 16:59 UTC Modified: 2009-07-03 20:27 UTC
From: php at pwnt dot be Assigned:
Status: Not a bug Package: PCRE related
PHP Version: 5.2.10 OS: All
Private report: No CVE-ID: None

The behavior described at 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]$/', '?');

Expected result:

Actual result:
PHP 5.2.8: 1
PHP 5.2.10: 0

This also occurs on Linux.

The reproduce code is broken (I cannot read the input character), but anyway if this is a bug, it's surelly not in PHP.
If you strongly believe this is a bug, please report it to the PCRE team.
