OperationalError: (sqlite3.OperationalError) Could not decode to UTF-8 column

I am new to odo. I have a simple function for migrating databases:

```
from blaze import Data, odo, like

def migrate(source, target, table_names=None):
src_db = Data(source)
tbl_names = (src_db.fields, table_names)[table_names is not None]
for tbl in tbl_names:
display("Migrating Tablename ::" + tbl)
odo?
odo('{0}::{1}'.format(source, tbl), '{0}::{1}'.format(target, tbl))

migrate(url_config, url_config_bcp)
```

Upon running this on a SQLite database.

```
url_config = 'sqlite:///DB_CONFIG.db'
url_config_bcp = 'sqlite:///DB_CONFIG_BCP.db'
migrate(url_config, url_config_bcp)
```

I get following error.

How can I resolve this ?

P.S :- I am aware that we can set textfactory expilicitly in sqlalchemy

```
db = create_engine('sqlite:///{0}'.format(sqlite_name))
conn = db.raw_connection()
conn.connection.text_factory = str
```

I don't know how to fix it within odo function

Reproduce the SQLite migration through migrate() and the odo(...) call, using the sample source and target URLs. Inspect how odo opens the SQLite connection and compare it with the SQLAlchemy raw_connection/text_factory setup described in the issue. Done means the migration handles the column's non-UTF-8 value without raising OperationalError.
