==Chinese/Japanese/Korean (CJK) Display Problems==

There is problem of Chinese, Japanese, Korean characters display on Java applets, the reason is either JRE could not locate the font files or the font files are not existing in the system.

The followings are not guarantee as the best solution. One should read and modify the font specification files (.src files located in /usr/java/jre1.5.0_06/lib (replace jre1.5.0_06 with current version).

Procedures to setup JRE on Firefox with Internationalization==

1. ensure JRE is installed.

2. ensure Firefox is installed.

3. ensure a true type font is installed on OS. (in this case, an Arial Unicode font file aka arialuni.ttf has been copied into ~/.fonts/ and fc-cache command was ran successfully.

4. create a "fallback" folder in JRE lib/fonts folder (for example: /usr/java/jre1.5.0_06/lib/fonts)

5. in the fallback folder, create a symlink to the .ttf font (for example, run this command in fallback folder in CLI: ln -s /home/cchance/.fonts/yourfont.ttf yourfont.ttf).

6. restart firefox and go to one of the above testing website.
