Pictures with Umlauts don't load on Linux

Linux is perfectly happy to have Umlauts in the file name line Zürich.jpg. Yet the Java JFileChooser refuses to see this as a valid filename. Not sure how to fix this. Update: I am experiencing issues with the Locale on my distro. Setting export LANG=en may help.

Often you will need to tell it where the javaws program was installed. On Windows do a search for javaws.exe. On Linux you can
find / -name javaws -print


Memory settings:

If you get out of Memory errors then you are probably best off using the local jar way of starting this application as you can then set the initial memory heap wit the -Xms and the maximum memory heap with the -Xmx parameters.

I have discovered the option -XX:+AggressiveHeap which sounds great for what JPO needs. Please let me know if you have issues with this.


Chinese Font

Franklin He has been kind enough to translate the User Interface to Traditional and Simplified Chinese. This looks really cool but poses some installation hassles if your Java system is not correctly configured. When I had a SuSE 10 system I had to create a /usr/java/jdk1.5.0_07/jre/lib/fontconfig.SuSE.properties file. Click here to download my version.

Please let me know of specific installation issues you have so that I may extend this section for the benefit of other users who might have the same issue.
