Some time ago I've written a command line script which we used to convert all our eZ databases to UTF8. It is made for running on a latin-1 (default) encoded database, so you will need to run it on the initial database. We've used it with success on 5 sites (2 rather big and 3 small ones). First it goes looking for all attributes who use utf8 encoded XML in the db. It will fetch them and reinsert their content into the db with latin-1 encoding. Then it uses the SQL command "CONVERT TO CHARACTER SET utf8" on all tables, which will convert all data to UTF8. As a final step, it again goes through all attributes looking for latin-1 encoded XML (the xml encoding attribute is not right now, since we converted everything to utf8 in the previous step). It will replace the iso-8859-1 string with utf-8 and then reinserts the data. I know the way this step is done now is not 100% safe, because it replaces every instance of "iso-8859-1" with "utf-8". But that was no issue for us.

If you want to run something similar on your database as it is now, you can try to use only the last step.
