Detect and convert bad encoded UTF-8 data in MySQL

-- Our lovely friends celebrate ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö \o/
-- Poor man's bad encoding detection (in my case there was LATIN1 data mixed with UTF8 in the database and I just wanted to find when things started to get mixed up)
-- When trying to convert, normally the amount of characters decrease...
SELECT field
