In other words, and this may seem harsh, the migration assistant is
pretty much useless for the majority of embedded hsqldb ODBs out there
in real-world actual daily use.

I would also add that every single table bar three (Customers,
Suppliers, Categories) we currently propose through the table creation
wizard in the Business category, has at least one of those fields, which
means that if people have used them in the past to create embedded
hsqldb files, they are all pretty much likely to fail on migration in
one way or another. I haven't checked the Personal category list of
tables, but I imagine it is a similar story.

In addition to what Drew outlines above, correct UTF and collation
support need to be guaranteed for all those who don't use ASCII English
in their DBs. We too often have a habit of forgetting that there are DB
users outside of the anglophone sphere, and their migration concerns are
just as valid.
