we're using jniregistry http://www.trustice.com/java/jnireg/ to read
registry values for things like folder locations. it has some bugs with
non-ascii chars (or encodings outside what's expected). there are some
hacks inside Base.java to get around them, but it'd be better to fix them
properly so that we can run on intl platforms more easily.

looking for help from anyone who in particular 1) has a japanese system
and/or 2) has experience dealing with the windows api and internationalization.

with the bug fix of #723, we've moved entirely to JNA, so the i18n issues
are now fixed starting with 0140 or so.
