SQLite needs UTF-8, but our internal representation is a superset of
UTF-8, so we need to decide what to do with the stuff that's beyond
UTF-8.  Does SQLite check this and return an error indication if the
byte sequence we feed it is not a valid UTF-8?  If it does check that,
we can rely on it, but we need to signal an error with a clear
explanation when it detects something like that.  Alternatively, we
should check this ourselves before calling SQLite, and signal an error
on our own.

One other comment is the use of fixnums for integer values.  Since
SQLite can use the full 64-bit width, I guess we need to use bignums
when the value exceeds a fixnum?

Thanks.
