True, but it should be noted (as they point out in the session presentation)
that normalization-insensitive is different than normalizing. So, if you
enumerate a directory's contents, the strings you get back for file names will
be exactly as they were originally passed in to the APIs and not necessarily
normalized. That means, if you compare against some other string, you will
have to do a normalization-insensitive compare to get the same "equality" test
that the file system uses. Mind you, you should basically never do that sort
of comparison. Always use the appropriate APIs to look up or compare file
system entries.
