Upgrading JIRA should convert the current encoding to UTF-8

Currently, for older JIRA there is possibility to use other encoding(eg: ISO-8859-1).In JIRA 4.4.x , the instance is set to use UTF-8 by default and there is no option to use other encoding.

For instance that is using other encoding that is upgraded to the new version, it will retain the current encoding and this cause some broken character(eg:Gadget)

Checking in the database shows that the webwork is not UTF-8:

select * from propertystring where id in (select id from propertyentry where property_key='webwork.i18n.encoding');

Updating the database manually and restart fix the problem:

update propertystring propertyvalue = 'UTF-8' where id in (select id from propertyentry where property_key='webwork.i18n.encoding');

So, it will be nice to have JIRA change all encoding when upgrading so that it is globally UTF-8.
