There is no need to implement it in the luatex engine as one can hook in code at all kind of moments (reading files, processing tokens, handling nodes) and no hard codes solution will satisfy each user and can only lead to weird hooks into and control over such a mechanism. The only thing luatex can do is to provide access to internals (which it does) and either library or lua code can do it's work. So, one can provide unicode bidi support to the extend needed.<br>
<br>
So the answer is: at the macro level (which includes the lua level).<div><div></div><br></div></blockquote><div><br>Thanks. What I am doing will be generic, so ConTeXt users can use it too if they like but to the best of my knowledge, most Persians use LaTeX. <br>
