infrastructure-content-disposition-csv-download-fails-with-500-error-when-dataset-nam-92c768b1

THEN Replace the naive 'content-disposition' header with RFC 5987 encoding: use 'filename*=UTF-8''<encoded_name>' and URL-encode the filename. This prevents the server from crashing on non-ASCII filenames.

import urllib.parse
encoded_name = urllib.parse.quote(f"{dataset_name}.csv")
headers = {"content-disposition": f"attachment; filename*=UTF-8''{encoded_name}", "content-type": "text/csv"}
