Thanks for the reply. It is much as I suspicioned. I do have Visual
Studio, and I was able to easily compile ICU with that, however it did
not give me an icudt that I could see. Perhaps I'd better look again.
Of considerable concern to me is whether I will be able to link
against that with gcc/g++ so I would rather use what I have currently.
I will try uconv and see what I get there.
