Thanks for the consideration. I threw my ego away years ago.

If you can look past my extreme opinions prefering common standards to
universal, I would appreciate hearing more about how you've managed your way
around the warps in the transformations. I think the folks at Sun and Oracle
might be interested, too. Have you tried sharing some of the key elements
with them, as a sort of bribe to get them away from trying to convert
surrogate pairs directly into UTF-8?
