Hello Eli,

Sorry to be late with my answer.

one based on overlays, which is what was originally suggested for this
purpose by Ken'ichi Handa, but is currently not working because the
characters in overlays don't participate in the bidi algorithm (Eli
thinks that would make things too slow).

If by "characters in overlays" you mean display strings,

I guess yes. To be very specific, it's the before-string and after-string properties mentioned on http://www.gnu.org/s/emacs/manual/html_node/elisp/Overlay-Properties.html.

then they are
not yet reordered because I didn't have enough time to make that
happen yet,

Okay, we'll wait. But please note that we are interested not in the reordering of the text inside each property, but in the text inside the properties participating in the overall bidi algorithm and reordering of the underlying text.

not because I think they would be slow.

If speed is no longer an issue, that's great.

Regards,   Martin.

If you mean
something else, you should know that overlays that specify other
properties _are_ supported.
