Re: [NTG-context] wrong behaviour with ConTeXt unicode bidi
I tried the latest beta; it fixes the problem I mentioned but breaks
something else:
\starttext
\setupalign[r2l]
\definefont[arabicfont][Arial*arabic at 20pt]
\setupdirections[bidi=global,method=default]
\hbox dir TRT{\arabicfont (1984)}
\stoptext
If you have \hbox dir TLT, you get expected result. I am not sure if this
is the side effect of using \hbox dir TRT.

One related question: is it possible to change font automatically when
luatex sees a LTR word?
no, but you can define start\stop commands that deal with such switches
also, you can combine fonts (and there a yet not documented auto
script/language switcher .. i have no time now to explain that one)
btw, never use \textdir and \pardir directly (i might even define them
as no-ops some day) but use the higher level alignment commands

the problem is that sometimes it's hard to deduce the state so i've added

\righttoleftvtop \rtlvtop

the other parsers do several passes and are slower can can handle some

[NTG-context] imposition 2SIDE: feature request
I know this is a bit silly, but maybe useful for a few people: the 2SIDE arrangement is nice for printing out and previewing book pages on A4 landscape. However, the arrangement has even and odd pages swapped. Would it be possible to define a scheme which does exactly the same as 2SIDE, but adds exactly one blank (unnumbered) page at the beginning of the document so odd pages end up on the right and every arranged page looks like a book spread?
