I must admit I have no idea what title-casing even is, but I'm eager to learn.
The documentation only talks about "words" and "first characters" and
"remaining characters." So a single character gets converted to uppercase,
whatever that may mean in the context of .title(). The .upper() method is
different in that it only applies to "cased" characters, so .title() may or may
not work differently on single characters.
