Titlecase has a different behavior than Rails

[lucianot]

I substituted the Rails titlecase method for UnicodeUtils::titlecase, because of UTF-8 characters. I noticed the behavior is not exactly the same, even when no special chars are involved. For example:

Capitalized letter within word:

> "CompanyName".titlecase
 => "Company Name"
> UnicodeUtils.titlecase "CompanyName"
 => "Companyname"

Words than contain periods:

> "Company X.Y.Z.".titlecase
 => "Company X.Y.Z."
> UnicodeUtils.titlecase "Company X.Y.Z."
 => "Company X.y.z."

Is this intentional for some reason? It would be interesting if unicode_utils preserved the original behavior and dealt only with the special chars.
