title: Should I use Python casefold?
body: <p>Been recently reading on casefold and string comparisons when ignoring case. I've read that the MSDN standard is to use InvariantCulture and definitely avoid toLowercase. However, casefold from what I have read is like a more aggressive toLowercase. My question is should I use casefold in Python or is there a more pythonic standard to use instead? Also, does casefold pass the Turkey Test?</p>
