Yuck! Yes, I see the same result with HanWangMingMedium. Note,  
however, that this font doesn't support the OpenType 'vert' feature,  
nor any vertical metrics, so it's not surprising that xetex doesn't  
manage to do a good job with it. I suppose I should do something  
about this....

I don't have the other two fonts you mention (yet), but I tried some  
other FZ... fonts that I have on Linux, and the results look OK.  
Note, though, that you need to include "script=hani" in the font  
declaration in order to specify the Han layout engine; without this,  
the 'vert' feature won't be applied, as it only exists within the Han  
script in the OT fonts.

Thanks - note that not all fonts listed there necessarily support  
vertical features, though - ymmv ;)
