In case you have (still) missed the point, the result of "Capitalize Every
Word" is not true title case, which is what the OP was asking about.
I didn't miss the point, but there are several conventions on how
"Title" is used. Capitalizing all words in a title has become
acceptable, but if you want to get technical, the following rules can
apply:
1. The "The Chicago Manual of Style" says the following about
capitalization in titles:
-Always capitalize the first and the last word.
-Capitalize all nouns, pronouns, adjectives, verbs, adverbs, and
subordinate conjunctions ("as", "because", "although").
-Lowercase all articles, coordinate conjunctions ("and", "or", "nor"),
and prepositions regardless of length, when they are other than the
first or last word.
-Lowercase the "to" in an infinitive."
As you can see, it can get complicated which is why many just
capitalize every word in a title.
