O, or is it 0? Bug or not?

I noticed that I somehow had 2 ship designs with the same name. I've been puzzling how it could happen but I just figured out that 0 and O look almost the same in SE5, so much that you can't really tell the difference. It seems to me this could be used as some way of tricking enemy into attacking what they know is an unarmed ship design when in fact it's a warship.
