Description
It appears the BAN API does not allow the "=" character within the multipart form boundary.
It appears this character should be allowed as referenced here (though comments on this post mention subtilities linked to the differents OSs). This would appear anecdotic but it can have serious repercussions (for instance, requests-cache needed a patch which is not yet released).
Code sample to reproduce the error:
import io
import pandas as pd
import requests
from contextlib import contextmanager
from urllib3 import filepost
csv_sample = """
