Aha; I've been able to reproduce the vertical-offset problem by  
updating to the latest Freetype2 release. With 2.1.10 (the installed  
version on my SuSE 10 system), it's fine; but relinking xetex with  
2.2.1 (latest from the Freetype project), I get the words set  
diagonally downwards.

I've checked-in a change to xetex that should correct this problem. I  
think freetype is arguably wrong to be returning non-zero advanceY  
when the glyph was not loaded with the VERTICAL_LAYOUT flag; should  
check into this more carefully. But this patch should keep the words  
properly on the line, anyway.

The character-mapping issue that some have seen is a separate bug,  
not yet fixed.
