I can confirm that this patch solves the issues I've had where I can submit multipart forms provided I have a string URL, but not if it's unicode.

I'm using Python 2.7.12. Applying the patch fixes the issue.

Code which breaks, assuming the file contains binary data:

# -*- encoding: utf-8 -*-
import urllib3
pool_manager = urllib3.PoolManager(num_pools=2)
url = u'' # removing the 'u' fixes it
content = open('/some/binary/file').read()
fields = [
    ('foo', 'something'),
    ('bar', ('/some/binary/file', content, 'application/octet-stream'))
pool_manager.request("POST", url, fields=fields, encode_multipart=True, headers={})
