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). I didn’t notice any issues with my test device using the developer beta of 10.3. He changed the file names from Arabic to Roman and then he said he could open them.

I’ll take a look at this today. I suspect I’m not using fileSystemRepresentation. I’ll have to see when that is appropriate to use as I believe I’m creating a URL from the string the user types in and then using that as part of the URL for the UIManagedDocument.
The person did create a new Arabic file under 10.3 and it opens fine, but the ones that we created under 10.2 won’t open under 10.3 unless the person changes the name so it uses Roman/English characters.
If using fileSystemRepresentation doesn’t fix it, I’ll file a bug.
