Not at all. But it would be nice if the extension did something intelligent when passed an IS_UNICODE string. IS_UNICODE strings don't just exist when unicode semantics are turned on either. So it actually doesn't matter if that switch is on or not, extensions should handle Unicode strings. -Rasmus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
