MySQL search and replace unicode (hexidecimal) characters with HTML entities

Not really pretty, but this will replace Latin-1 Supplement and Latin Extended-A characters (plus permutations of quotes, dashes and apostrophes) with their corresponding HTML entities. NOTE: if you use this, copy the queries from the source code of this page, the browser is translating the entities. Query is operating on a column called DESCRIPTION.
