I picked a couple of test cases, found them to not do the case insensitivity special cases, and concluded that I don't understand Windows' file system case folding (with the possibility that it's an ASCII-only case fold). Anyway, it's still not something I would recommend; if you want true case folding, you need to go the whole way - and it still has problems.
