This seems to be a little bit different from the standard. First,
SQL_TEXT is not equal to ascii. It's a subset of ascii. Second, the
default charset for char and varchar might be implemenation dependent,
not neccesarily limited to SQL_TEXT. The only requirement is the
charset must contain the repertoire SQL_TEXT has. I think any charsets
including ascii I've ever seen satisfies the requirement. Third, the
standards says nothing about locale.
