.title() - annoying mistake

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.
