Is the question, what is canonical mapping? I'm going to assume it is, so I can share what I found when I hit much the same issue. This is mostly from memory so let's hope it's right. Take the word Café. How many Unicode characters is this and what are they? Turns out there are two answers. The la

Unicode filenames with Apple File System and UIManagedDocument

I have an iOS app (Attendance2) written in Objective-C. One of my users upgraded to the public 10.3 iOS beta and reported he could no longer open his documents (I have a subclass of UIManagedDocument so they are Core Data files stored in the package/directory format that UIManagedDocument uses).
