I think I found a bug in EncFS under OS X, but don't know where to report it. If it can be reproduced, the How-to on this website should contain a warning.
Under Linux, I create a folder called "ä". Then I put some files into this folder. On OS X, the folder "ä" shows up, but appears to be empty. Then I rename the folder to "a" on Linux, the content shows up on OS X. If I rename it back on Linux to "ä", the content is gone again. If I try to rename the folder under OS X, I get an error message.
To me, this looks like a bug in the OS X version of EncFS. I know that this is not directly related to BoxCryptor, but it might affect it's users so it's important.
Can anyone reproduce this bug? Any solution for this?
