I was trying to get some simple skeleton stuff in from the older
patches but I'll see what I can do for Unicode support.

Right. The UCLA code has more support for dumping the info to an xml

/t, etc., though both that and no switch both return 0, so not a big
difference in practice as you pointed out.
