Naming looks OK....

This looks like a problem with a kerning table in the font. I can't  
tell from the report here whether there's something wrong with the  
font itself, or with the ICU library functions that interpret it. If  
you can run MS Font Validator on the font, it would be interesting to  
see what it reports.

I'm not familiar with this font; is it a freely available font that I  
could take a look at, or a commercial product?
