File translator override for encoding defaults to UTF-8 in Designer but doesn't write to the vdb.xml

If you need to override the file translator's encoding value and want to set it to UTF-8, the Designer shows this value as the default so will not write it to the overrides in the vdb.xml and hence the server will not look at it. Can the default in the Designer be blank? so that any value entered will be written as an translator override in the vdb.xml file.
