Why does Rails titlecase add a space to a name?

Question

Why does the titlecase mess up the name? I have:

John Mark McMillan

and it turns it into:

>> \"john mark McM         


        

Answer 1

The documentation for titlecase says ([emphasis added]):

Capitalizes all the words and replaces some characters in the string to create a nicer looking title. titleize is meant for creating pretty output. It is not used in the Rails internals.

I'm only guessing here, but perhaps it regards PascalCase as a problem - maybe it thinks it's the name of a ActiveRecordModelClass.
