Phony Format Font > Capitalization
I used Format > Font > Capitalization > Title Case to format a column of cells. Looks nice in Numbers, but the underlying capitalization styles still exists if I export to CSV or copy & paste to a different app (ie., if some text was all capitals, it exports as all capitals instead of title case).
How can I really convert the text to title case (or any other other capitalization styles that I choose)?
