if you really want to use latin-1 in the database, and you don't mind dropping
unsupported characters, you can use

    text_extrated = text_extrated.encode('iso-8859-1', 'replace')

or

    text_extrated = text_extrated.encode('iso-8859-1', 'ignore')

a better approach is of course to convert your database to use UTF-8 and use

    text_extrated = text_extrated.encode('utf-8')

it's also a good idea to switch to parameter substitution in your SQL queries:

    cursor.execute ("update ... set text = %s where id = %s", text_extrated, id)

it's possible that your database layer can automatically encode unicode strings if
you pass them in as parameters; see the database API documentation for details.
