Status: | Open | Resolved: | |
Product: | iOS + SDK | Product Version: | iOS 10.3 (14E5249d) |
Classification: | Serious | Reproducible: | Always |
Area: Something not on this list Summary: If you use legacy stdio functions for writing to non-ascii filenames, the filesystem enters a weird state, where NSFileManager can list the file, but checks if it exists fail. Steps to Reproduce: 1. write "hello" to file named "acentuação.txt" with fopen/fwrite/fclose 2. list files available with NSFileManager contentsOfDirectoryAtPath:error: 3. check if the single listed file exists with NSFileManager fileExistsAtPath: Expected Results: the file should exists, since we had it returned by contentsOfDirectoryAtPath:error: Actual Results: the file does not exist Version: iOS 10.3 (14E5249d) Notes: Xcode example has been attached where the error is provoked in application:didFinishLaunchingWithOptions: Problem seems to happen only on iOS 10.3 no matter what device, as long as it is on device. It does not happen in the simulator. Configuration: iPad Air 1, 32GB cellular

[Closed] [DUPLICATE OF 30735074 (OPEN/CLOSED)]
Apple closed the radar marking it as a duplicate of 30735074.
Since the bug is still present, I will keep the status Open on the openradar entry and will return to edit when a actual fix is out.
I agree and somehow the method name shaped my language. Hoping the bug can be understood despite this.
"Actual Results: the file does not exist"
That's not the result. The result is that fileExistsAtPath: claims it doesn't exist.
