I was wrong here. The CJK fitter uses the same routine as Latin fitter
to detect segments and edges. 

The real problem is that the Latin segment detector cannot find the
terminal segment if there is a slight curvature there. That's, if there
is slightly off the spline control point between the 2 anchor point of a
terminal segment, the segment cannot be detected. As shown in the
attached example. 

If someone can improve this situation, it will be greatly appreciated.
