Correcting the UTF8 conversion

The previously posted script switched to many unnecessary fields to UTF8. This seems to have degrade performance considerably as the size of the tables increased dramatically. (3x more space is allocated for every field in UTF8 when compared to latin1). To revert to 'latin1' charset and only change the most necessary fields, run the following script, just change the first line to fit the name of your database.

alter database openfire charset=latin1;

alter table ofUser charset=latin1;

ALTER TABLE ofUser CONVERT TO CHARACTER SET latin1;

alter table AtomPerson charset=latin1;

ALTER TABLE AtomPerson CONVERT TO CHARACTER SET latin1;

alter table FullNameField charset=latin1;

ALTER TABLE FullNameField CONVERT TO CHARACTER SET latin1;

alter table NameField charset=latin1;

ALTER TABLE NameField CONVERT TO CHARACTER SET latin1;

alter table NoteField charset=latin1;

ALTER TABLE NoteField CONVERT TO CHARACTER SET latin1;
