If you think that's working, you're not testing enough.

If you use ">" or "<" or ORDER BY on those fields, and the
fields actually have UNICODE data in them, the results will be weird.
None of the string operators, like CONCAT, will work right.

If you're going to treat UTF8 data like that, you might just
store it as a BLOB, viewed as opaque by the database. That
locks out all the operations which will do the wrong thing on
misinterpreted data.
