Bug persists in Intrepid. I wonder why we only just recently had this problem reported, and only now found the workaround. Is this an Ubuntu-only thing? Do not many people use OpenJDK?
In any case, the workaround does work, except that I tweaked it to be en_US instead of de_DE. I'm attaching two screenshots of Anathema v1.3.1, a program for managing characters in the like for the tabletop game Exalted. One is pre-workaround, and one is post-workaround. I added "export LC_ALL=en_US.ISO-8859-15" in the included anathema.sh right before the line that runs the jar.
I hope a proper fix comes soon. :)
