There is no default collation imposed by Cook.
It will create from the default collation of your database.
All my components tables are in UTF8, generated by Cook.

About UNIQUE :
It will be available in 2.0, and I think also with an Ajax facultative query directly in the validator ;-)

EDIT : It is not done yet, because of the sandbox restoring datas.
If you define an UNIQUE after having inserted datas, the system can crash on restoring, so I am currently building a restoring process that will add suffixes to the datas to keep them uniques, or to skip them when impossible to add a suffix (int, fk...)
Well it is not easy to go around all kind of possibilities that the user can create :unsure:

Coding is now a piece of cake
