-Status: Open
+Status: Bogus
Bug Type: PCRE related
Operating System: Windows XP SP2
PHP Version: 5.2.5
New Comment:
In PHP 5.2.5 we upgraded PCRE to version 7.3. This version has stricter
UTF-8 string validation, and thats why the string is now rejected.
For the record this bug has nothing to do with the mbstring extension.

I think it is a bug because, when the script is tested within version
5.2.4, it returns true.

I've got the same error on linux (Debian Etch).
But your pattern (and your subject) is not a valid utf-8 string.
I've checked that with : mb_check_encoding("\xf8\xa1\xa1\xa1\xa1",
'UTF-8')
and it returns false.
So, I think it's not a bug.

Description:
------------
In a test script, I call preg_match() function, using the flag u, in
order to test an UTF-8 regular expression with hexadecimal characters.
Of course, the mbstring extension is loaded and active.
Reproduce code:
---------------
$mb = function_exists('mb_detect_encoding');
$pregutf8 = preg_match("/\xf8\xa1\xa1\xa1\xa1/u",
"\xf8\xa1\xa1\xa1\xa1");
Expected result:
----------------
Returns true for both variables.
Actual result:
--------------
Returns true for $mb.
Returns the following warning message for $pregutf8: "Warning:
preg_match() [function.preg-match]: Compilation failed: invalid UTF-8
string at offset 0"
