I'm having an issue with an app (not sure if it matters which one, details below) saving files with diacritics in the filenames. I've run into numerous examples and have observed the following among other things:

  1. files so-named (including folders and contents) are completely invisible to MacOS Finder (and Finder replacements like ForkLift) [MacOS Sonoma]
  2. they do not turn up in searches with File Station on DSM 7.1, even searching within their parent Folder, and even searching a non-problematic word in the file name (eg "Submarine" in example)
  3. they do show up when scrolling the file list in File Station.
  4. if renamed in File Station to a name without the diacritics, they still do not turn up in the search (2); cannot download to Mac
  5. other odd behavior as above if such a folder is zipped (compressed), but zip file can be downloaded to Mac.
  6. unzipped on Mac there are no other apparent issues in Finder
  7. all files show up in a MacOS Terminal listing (ls) as here:
Code:
% ls | grep Submarine
The Marias - Submarine (2024) - WEB V0.zip
The Marías - Submarine (2024) - WEB V0
The Marías - Submarine (2024) - WEB V0.zip

The "Marías" is a simple example of this problem. (note renamed version without diacritics -4).

I've had same problem with other types of diacritics in filenames.

The app in question is Transmission 4.05 running in a docker container. I suspect similar problems with any app that would create such filenames.

Questions:
  • Is this an issue with DSM or with Transmission or both?
  • Suggested fixes?

PS: tried to do this to determine encoding but 'cannot open'

Code:
file -bi 'The Marías - Submarine (2024) - WEB V0'
cannot open `The Marías - Submarine (2024) - WEB V0' (No such file or directory)
