[XeTeX] Advanced East Asian typesetting

[Gerrit]

Hello List,

Sorry, I didn’t follow the discussions here for quite some time now, so I 
don’t know the current state.

I wonder if it is now possible to conveniently typeset CJK?  I’m especially 
interested in vertical typesetting and ruby, and also about „good“ line 
spacing, kinsoku shori and such. 

Is there maybe some package for this, where I can just enable \vertical and 
Xelatex sets everything vertically?

All I know until now is „\XeTeXlinebreaklocale“, but apart from that, nothing 
:(

Extremely nice would also be typesetting Mongolian and Manju, does anyone know 
something about that?

Thanks!
Gerrit
