Yes, but in this case Python is wrong.

Titlecase should, at least for Unicode strings, follow the Unicode "Default 
Case Algorithms", see bug http://bugs.python.org/issue6412.
http://www.unicode.org/Public/5.2.0/ucd/DerivedCoreProperties-5.2.0d15.txt 
lists:
0027          ; Case_Ignorable # Po       APOSTROPHE
An as such the following would be correct:
>>> "He's a great guy".title()
"He's A Great Guy"

I'm not subsribed to the list, CC me for answer.
