Well, the obvious original reason is that ICU uses UTF-16 internally and the logic was that we would be going in and out of ICU to do all the various Unicode operations many more times than we would be interfacing with external things like MySQL or files on disk. You generally only read or write a string once from an external source, but you may perform multiple Unicode operations on that same string so avoiding a conversion for each operation seems logical. -Rasmus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
