Anyone know what the exact behavior of NSLiteralSearch is when calling -[NSString compare:options:]?
I need to sort an array of NSStrings, with the ordering based on a raw comparison of UTF-16 character values*. That is, sorting the strings as though they were just arrays of UInt16, instead of using any kind of Unicode smarts or locale-specific settings. It sounds as though NSLiteralSearch does that, but the docs don’t actually spell it out.
