I just upgraded from Xamarin 184.108.40.206 to Xamarin 220.127.116.11 and my Pdf with an accent in the file name won't open anymore when using UIDocumentInteractionController. The problem only occurs on my iPad and not on the simulator.
# Steps to reproduce
Run the attached project.
# Expected behavior
To open the Pdf
# Actual behavior
It shows a grey screen instead of the Pdf
# Supplemental info (logs, images, videos)
If you change the documentToOpen to "documentPdfWithoutAcuteAccent" it works. But removing the accent is not a solution. In my real use case, the Pdf are downloaded from the user's Dropbox so I have no control over the name.
I also added some tests in the attached solution:
"File.Exists(documentPdfWithAcuteAccent)" and "File.Exists(documentPdfWithoutAcuteAccent)" both return true, but "fileManager.FileExists(documentPdfWithAcuteAccent)" returns false and "fileManager.FileExists(documentPdfWithoutAcuteAccent)" returns true.
I think it is a problem with NSUrl or NSFileManager because it can't find my Pdf file with an acute accent. Or there is something not consistent between .Net and iOS
# Test environment (full version information)
I tested on an iPad model MD788CL/B running iOS 10.3.1

This is due to the new file system (APFS) that Apple introduced in iOS 10.3. Sadly Apple did a bad job at explaining the impact of the new file system.
More details in https://mjtsai.com/blog/2017/03/24/apfss-bag-of-bytes-filenames/
Is there a workaround to this problem?
