MacOS: Can't delete diacritically named files (NFC unicode form)

[eugenesvk]

On macOS if I copy an NFC composed unicode form file with some diacritics (e.g., ü which is composed of 1 "composed" symbol) to a mounted Gocryptfs volume, I can't delete it in a file manager (even if I can delete the same file in the same with the same NFC form), though can delete it in a terminal

This might be a limitation of the upstream macfuse/macfuse#954, but I can create/rename such files, just can't delete them, so maybe it's a different issue?

I'm sorry, I have no idea, and I also don't have a Mac to test. Best I can do is to leave this ticket open so other people can find it.

@eugenesvk Could you maybe provide shell commands to recreate the problem you're having?

[eugenesvk]

The issue exists for some cli apps as well, so if you install this https://github.com/sindresorhus/macos-trash (binary is trash) and do this you won't be able to delete the file

touch 'Terminal 1ü 2ü'
trash './Terminal 1ü 2ü'

You get the following error
The file “Terminal 1ü 2ü” doesn’t exist.

Repeat the same in a regular folder (non-gocryptfs-encrypted) and it works fine. The name consists of 1-symbol precomposed letter 1ü and a letter composed of 2 symbols 2ü
