### Steps to reproduce

I tried to transfer via the automatic upload the folder
"Internal Memory/Pictures/" to "/Photos/FotoArchivioSD/Pictures/" files were correctly trasfer but I noticed that a specific folder were missing many files. In particular, I noticed the subfolder
"Marocco 2024🪬/" only 4 files were trasfer, when actually using external file manager I could see about 400 files.

Then to make the automatic upload only with the single custom folder
"Internal Memory/Pictures/Gallery/owner/Marocco 2024🪬/" directly to the folder "/Photos/FotoArchivioSD/Pictures/Gallery/owner/Marocco 2024🪬/" but again only 4 files were transfered out instead of about 400 files. Actually, when I tried to add custom folder Nextcloud app was able only to see 4 files in the local folder, when other file manager were able to see about 400 files.

### Expected behaviour

It should transfer all files and not just the firsts 4 files.
Nextcloud Android should be able to see all files in a folder even if a special charter like the emoticon ("🪬") is in the path.

### Actual behaviour

Only 4 files were transfered instead of about ~400 files.
Only 4 files were seen by the Nextcloud Android locally (when actually an external file manager can see ~400 files).
