I'm trying to convert strings to Title Case, but getting ugly results

"I Can'T Be Having With This"
Anyone have any suggestions for working around this?
A bit of regex?
import re
def title(string):
return re.sub(r"\b'\w", lambda m: m.group().lower(), string.title())
Nice. It lowercases a word char that follows an "'" that follows a word
without an intervening non-word char. It passes this test:
print(title("'time' isn't 'timeless'!"))
'Time' Isn't 'Timeless'!
It guess the reason not to bake this exception into str.title is that it
is language specific and could even be wrong if someone used "'" to
separate words (perhaps in a different alphabet).
