The unicode2iso Plugin for CodeIgniter is a simple plugin that allow you to covert an UTF-8 string containing HTML into an ISO-8859-1 string using HTML special chars without stripping the HTML of the original string.

You have to set manually in $retrieve all HTML elements wich you allow to be retrieved.
