If you want to have UTF-8 support on Windows machines (and maybe others), you'll need to use the native app, or you'll have to add -Dfile.encoding=UTF-8 to your JAVA_TOOL_OPTIONS environment variable. This should be documented clearly, probably in the quick start guide, and certainly in the longer documentation... once it exists.
