Btw, is it not limited to BMP (basic multilingual plane) characters?
All unicode characters can no longer be represented in 16 bits
(supplementary characters since Unicode 3.1 - code points above
U+FFFF). I guess since this was only added to Java in 1.5 (which
supports Unicode 4.0), Derby does not currently handle such
supplementary characters?
