It's unclear what you mean by "that is actually how it is spelt"; we're talking about typography, not spelling.  The former has to be in accordance with our MoS, the latter is a different matter; if the programme were called "Dinerlaydies", that's what we'd call it.  If Dickens wrote "A tale OF two cities" on his manuscript, we'd still call it A Tale of Two Cities.   (Μελ Ετητης)
