The real reason Python strings support a .title() method is surely
because Unicode supports upper, lower, _and_ title case letters, and
tells you how to map between them. Consider:
>>> '\u01f1'.upper()
'\u01f1'
This is the "DZ" character.
>>> '\u01f1'.lower()
'\u01f3'
This is the "dz" character.
>>> '\u01f1'.title()
'\u01f2'
This is the "Dz" character.
When you write that code to capitalize your book titles, you should be
calling .title() rather than .upper() if you are doing it right.
But that's exactly what he's doing, with a result which is documented,
but not really satisfactory.
