Title: Use fully defaulted charset for char width computation.

This is only an issue with specially-created tables, such as those in unit tests and system tables. Full AIS tables get the charset & collation resolved and then saved.

This will matter when charset is inside tInstance, and so always present.

Adjust tests to either pick an SBCS or expect increased size.
