All kinds of chinese glyphs do not render correctly using Java 2D. The pieces
that make up the glyphs seem correct, however their relative positions are all
wrong. I'm guessing that this is a bug in the treatment of composite glyphs?

Below is a small Java application that displays two characters that I've had
trouble with on the screen using Java 2D.

Note that the glyphs are incorrect at the Shape stage - as I've used another
method to render Shapes that also revealed this problem.
