I'm sure you are right (I started this adventure by using the official
Unicode database, but that didn't quite match .NET 3.5 SP1), and hope
that accounts for the substantial changes in v4.0.

Should I aim to support 4.0 only, provided it is closer to the UCD?  (I
would still have to check that.)

Cheers,
Damien
