Hi Peter,

> our UTF-8 is strictly speaking CESU

Errr...sorry to be dumb, but what is CESU?

I have finally narrowed down what our immediate requirements - to
support simplified Chinese, and Korean.

I've been doing a lot of digging, but getting pretty confused! Can
Firebird handle this? Is there any problem interacting with
Firebird through Java (doesn't Java support UCS-2?)?

Many thanks for any light you can shed!!
