It seems to me that the change might be caused by item 9 in the
changelog of Version 8.10 25-Jun-2010[2].

It seems that behavior changed in 5.3.4 (PCRE updated to 8.10). However, I couldn't see
relevant changes that cause this. Will look further, if anything, docs can be updated to reflect it.
Thanks for report.

Description:
------------
The PREG manual states[1]:
| In UTF-8 mode, characters with values greater than 128 do not
| match any of the POSIX character classes.
However, that is not necessarily true, so the statement should be
changed appropriately.
Test script:
---------------
var_dump(preg_match('/^[[:alnum:]]$/u', "\xc3\x84"));
Expected result:
----------------
int(0) // expected according to the current documentation
Actual result:
--------------
int(1)
