Uploaded file in FileFIled with an 'em-dash' fail swhen retrieving from file storage

Which tool versions are you using?

SDK: v14.28.0
Platform: v26.08.3
Python: v3.14
Isolation mode: venv

Current Behavior

File(Fields) which have a file with a name that contains an ‘em-dash’: – fail on the back-end. Apparantly this is a forbidden character, but there is no mechanism preventing you from uploading such a file. In our current LLM age the character is used more then ever.

Expected Behavior

Either a warning on upload, or a replacement on upload.

Context (optional, but preferred)

viktor._vendor.requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://viktor-storage-eu1.s3.amazonaws.com/filefield-storage/
