Interesting.  I never thought it was an FB translation issue.
I just concluded that I was overlooking something simple.  I've
played with this example and the CoreText Arc example.  It's sad
to say but since I haven't done any real Mac programming in a few
years, I'm forgetting to do some things to help troubleshoot, such
as using the C examples.  I've been so focused on getting up to 
speed in FB again, (having to use Java for school) that I didn't 
think to modify the C examples that I have.

Thanks for confirming that I wasn't really lost, it just didn't work.

Experimenting with C instead of FB, by hacking this demo:
<http://developer.apple.com/samplecode/CoreTextTest/index.html>
shows that kCTFontWeightTrait, kCTFontSlantTrait and kCTFontWidthTrait  
do nothing.

kCTUnderlineStyleAttributeName works but ignores kCTUnderlineStyleXXX  
and kCTUnderlinePatternXXX.
These are exactly the results you get. The conclusion, reached with  
some reluctance, is that there's nothing wrong with your code or  
FBtoC's translation of it. Maybe it will work in Snow Leopard?

In the meantime, you may have to settle for colour instead of  
'styles'; kCTForegroundColorAttributeName works.
