yes, whoosp, just found that page. the problem turns out to be
that isset($string{n}) is always false with ZE2, and empty($string{n}) is
always true. same for $string[n]. it works with ZE1, so i'll
just log the bug.
(though it does kick out an 'Uninitialized...' notice, which the same
test on an array key or object property does not. i sympathize with the
bugs that have been logged about that, which have generally been marked
Bogus. but that can be suppressed with @, at least, so not a big thing.)
