Unicode NFC file names

[ManfredXG]

Hi, I'm new here ...
Many many tanks for this piece of software.

[ Hint: NFD stores ü as 0075 0308, NFC stores it as 00FC ]

I have an idea to improve it (in my view):
When you create/rename folders/files, Nimble Commander always uses NFD-names (like Mac Finder).
The MacOS-Terminal uses NFC or NFD, depending on what you type.
I know, MacOS is storing both, but ls-command and C-readdir()-function deliver the primary name-form.
My suggestion:
Either like Terminal or to have a switch (Always NFD, always NFC, as typed in)
What's your opinion to this?

Hi, you're welcome!

IFAIK filesystem paths should be always decomposed on MacOSX:

• https://github.com/apple/swift-corelibs-foundation/blob/ca3669eb9ac282c649e71824d9357dbe140c8251/CoreFoundation/String.subproj/CFStringEncodings.c#L1011

• https://developer.apple.com/support/downloads/Apple-File-System-Reference.pdf
  etc...

Why do you care about the normalization method in the first place?

Hi,
after calling C-function readdir() my program has to convert from NFD to NFC.
That would then be unnecessary.

And what this has to do with either MacOSX or Nimble Commander?
If your code needs a Unicode string in a specific normal form - this normalizations has to be performed by that program.

From your point of view, you're right.
But I think, it would be a great feature.
Mac-Terminal has this feature and I like it.
But it's not "vital" for me, only nice to have ...
