There have been a fair number of behavior bugs with respect to cursor positioning (that's the tricky part of your changes, and IIUC the only part that can't just be turned off by bidi-display-reordering), but they seem to be mostly under control now (new cursor bugs are just as likely now to exist in Emacs-23 as well). The other source of problem has been performance, and AFAICT it's always been linked to bidi-paragraph-direction (unsurprisingly: the rest of the changes have almost no impact on algorithmic complexity, and even the potentially large slowdown on the core "step to next position" operation is drowned in all the rest of the work we do per-position anyway). We can make that default to `left-to-right' if needed, but hopefully that won't even be necessary. Stefan
