send_direct_message and ValueError: Only unicode objects are escapable.

[patricktokeeffe]

I'm following the simplest examples but cannot get direct messages working.

With a conf.py containing (well, with real keys):

#visit http://dev.twitter.com to create an application and get your keys
consumer_key =          'xxxxxxxxxxxxxxxxxxxx',
consumer_secret =       'xxxxxxxxxxxxxxxxxxxx',
access_token =          'xxxxxxxxxxxxxxxxxxxx',
access_token_secret =   'xxxxxxxxxxxxxxxxxxxx',

This script fails:

from conf import (
    consumer_key,
    consumer_secret,
    access_token,
    access_token_secret
)
twitter = Twython(
    consumer_key,
    consumer_secret,
    access_token,
    access_token_secret
)
twitter.send_direct_message(screen_name="patricktokeeffe", text="first test!")

..with this traceback:

I think this parallels #121, but I can't tell what requests is choking on.

Can you pip freeze so I can see which versions of twython, requests and requests-oauthlib are being used?

[patricktokeeffe]

OK thanks for waiting. My requests is really old, turns out 👇. Unfortunately I won't have time to upgrade and retest until Friday.

Just hit this myself, with these versions on the most basic example.

requests==2.18.4
requests-oauthlib==0.8.0
python-twitter==3.4.1

using Python 3.6.4, doing the most basic postmessage example :/

Actually this seems to be in the twitter library itself
