It turns out that the font does have some less-than-ideal adjustment 
instructions in the OpenType tables; some irregularity can be seen at 
certain sizes on Windows. But there was a specific bug in the ICU 
library that caused this drastic misplacement of the marks; I've just 
fixed it, so it'll be correct in the next release (shortly).

Thanks for the report; that was a strange one. (If you try other point 
sizes, you'll find that the problem occurred only with certain glyphs 
at particular point sizes...but different sizes for different 
characters!)
