Hi Ron,
In book 1 we do not go into great depth about internationalization. One of appedix deal with Unicode characters. However, we will discuss Internationalization in greater depth in book 2 which is due out in a few months. Of course it helps if you are able to support us by purchasing book 1 ;-)
If you're working on anything in particular feel free to send the query and we'll take a look.
all the best,
