OK, here what should be done (Unix):
1LANG=en_US.UTF-8
2LC_CTYPE="en_US.UTF-8"
3LC_NUMERIC="en_US.UTF-8"
4LC_TIME="en_US.UTF-8"
5LC_COLLATE="en_US.UTF-8"
6LC_MONETARY="en_US.UTF-8"
7LC_MESSAGES="en_US.UTF-8"
The point is to run the appserver on locale with UTF-8 encoding. Second, I also gave appserver an option "file.encoding" that points to "utf8" (just to be sure). Now it works fine. However, I think Zip writer should put this by default, overriding everything from the system!!!
