You may not have the font on your machine. Swing/awt will substitute a font that's "close". The substituted font on your machine may not have glyphs for the chinese characters. Check what's in your jre/lib/fonts directory vs what's in the developer's. Likely the jre/jdk he installed has gobs more fonts, and the font files are much larger.

You don't specify a font in your tester; you use the default for the JOptionPane. Looks like your developer specified a different font, or the default fonts are different on his machine.

Subject: Weird problem with a Java program accessing AS/400 Unicode data, but failing to render Chinese characters

We're having a problem with a Java program displaying Chinese characters
in a Unicode field.

I've posted a more detailed description of the problem here, complete with screen shots and a source listing of a test program:

but basically, it appears that on a Chinese developer's machine (in China), everything works just fine. Yet on my machine, I get "substitute boxes" instead of Chinese characters, even though neither Firefox, nor a test Java application I wrote using Swing, has any trouble at all displaying the very same Chinese characters.
