My Chinese/CJK font has problems: why all fonts are shown as small squares?

Your Java has not been properly internationalized in your Linux/*nix system. Please check your Java's Chinese setup. We recommend you to use Sun Java 1.5+ as your Java version, The simplest font display's solution for the Java1.5 fonts are: Create a folder named fallback in $JAVA_HOME/jre/lib/fonts/; after that, please copy or soft link your Chinese font file into this directory.
