An implementation of Unicode Bidirectional Algorithm[1] and automatic,
script based font switching, Unicode Script Property[2]. Editing mixed
RTL and LTR text is mess already, adding to the mix LTR TeX commands for
every directionally switch makes it a nightmare. I ended up doing my
first pass without any directional commands at all then using some
regular expressions to post process the text, but this is no fun and
needs manual review not to mention that post editing that text still a
nightmare.
I've attempted to write the BiDi implementation several times myself, by
never managed to actually allocate enough time for it. ConTeXt already
has a BiDi implantation (typo-mir.{lua,mkiv}), but I gave up using it
because it is buggy and can be hardly used for any thing.
