        Work around a couple of problems in SQLite that maybe pysqlite
        should take care of: give it True and False and it thinks
        they're column names; give it Unicode and it tries to insert
        it in, possibly, ASCII.

            >>> meth = SqliteDB(db='nonexistent')._py2sql
            >>> [meth(x) for x in [True, False, 1, 2, 'foo', u'souffl\xe9']]
            [1, 0, 1, 2, 'foo', 'souffl\xc3\xa9']
