The fact automatic direction change is hardcoded is a serious drawback, and not and advantage, imo. There are many subtle points in bidi typesetting which can be addressed only in a programmable environment, like that provided by luatex. Even with otps, which are very limited as compared with luatex, I managed to implement a preliminary automatic direction change (in fact, an automatic script change, including direction).
I believe the automatic direction change is the main advantage otherwise typesetting with TeX is unnatural and useless. _________________________________________________________________ Holiday cheer from Messenger.
