Which is why we need the unicode=off switch. I don't think there is any way we can make Unicode PHP as fast as non-Unicode PHP. For people who need Unicode support, Unicode PHP will be faster and easier than any other way for them to get there, but for people who have no need for Unicode it would be really nice to maintain the fast non-Unicode mode. -Rasmus
