The "vertical" XeTeX feature is at least needed. +vert or +vrt2 is not
mandatory, as not every Chinese font has this feature, such as SimSun
and alike shipped with Win XP. However, for correct positioning of
punctuations, +vert or +vrt2 is needed.

I think it's easy to use RawFeature in fontspec to specify what
features you need. And +vhalt is also useful in some cases :)
