No, that was the issue you raised on the luatex list threadhttp://tug.org/mailman/htdig/luatex/2011-July/003192.html it's not buggy, just not as you expected. See Taco's comment towards the end of that thread. The interactions of the various direction primitives are not always intuitive (but that possibly can't be helped) and doesn't imply a bug. See also the thread around http://tug.org/mailman/htdig/luatex/2012-December/003957.html David -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
