at Korean/Solaris6/sparc and i386/eucKO:

korean font plain 10 display empty for all 2d textlayout test.
(TextLayoutRenderTest1.java to TextLayoutRenderTest10.java)

other solaris os has not this problem.

this can be reproduced by running:
%run_gs.sh test/font-render/2d/one/TextLayoutRenderTest*.java

* should be 1 to 10
run_gs.sh is command of global suite.
