Unfortunately PI Vision replaces additional spaces which is relevant for most of the scenarios. To achieve desired functionality of having more spaces i would request you to create an AF attribute with string datatype and include additional spaces and add to your display as value and hide other properties in visibility section except value. Hope this helps.
Can't see how removing spaces that have been deliberately manually, inserted is relevant for any scenario. If I stick in spaces manually, then you can bet your bottom dollar that's what I want. If it really is the case that people are incapable of correctly typing in single space characters, or that for some reason someone pastes in a field with unwanted space characters, then that could be an option to be selected. These spaces actually exist (if I re-edit the field, there they are) - as I said - I really don't see why anyone would assume a manually entered text field should, by default, be messed about with! If something within the PIVision does this for any string it tries to render, then the text formatting functionality should be able to circumvent that (using  's perhaps). It seems rather more like a bit of lazy implementation!
