It'd work with codepoints, but it strikes me now that this would be a job for UStrings. We could have u($some_input)->codePointAt(7) alongside u($some_input)[7]. Since UString works with codepoints and is guaranteed to be Unicode, this works. -- Andrea Faulds http://ajf.me/ -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
