I'm not sure of this myself as this is the first time I'm sorting unicode strings.
But after brief testing, calling compare: or compare:options: with NSLiteralSearch appear to do the same exact thing. This makes sense as the docs mention:
"Search and comparison are currently performed as if the NSLiteralSearch option were specified. As the Unicode encoding becomes more widely used, and the need for more flexible comparison increases, the default behavior will be changed accordingly."
So the final code I'll use will just be compare:. That way, I'm ensured to always use the default behavior.
