Amit Aronovitch also reported that rendering and cursor movement are ok on Debian. So, I suspect that the problem is specific to Windows. In Emacs, bidi reordering is done by Emacs itself, so the `shape' method of font backend should not reorder glyphs. But, perhaps Uniscribe backend reorders Arabic text, right? --- Kenichi Handa handa@m17n.org
