The characters other than ascii can't be displayed on the Component.

Any characters other than ascii can't be displayed on the Component
with set/get methods on Solaris

For example, the following button doesn't display title string.

new Button(XXXXXXX);
                   ^^^^^^^^
                   Japanese characters

Sytem.out.println() or Graphics.drawString() method works.
I guess awtJNI_MakeMultiFontString() in multi_font.c has any problems.
